TSA Checkpoints: A Modest Proposal

A LinkedIn associate and I have an idea for re-branding TSA Checkpoints as a nation-wide franchise of Department of Healthy Screening clinics...


We'll have you on your flight in no time!

"Did anyone else catch today's story about the possibility of screeners doing DNA swabs? Great news! If we hold out long enough, those pesky insurance co-pays will disappear and we can have all of our health screenings, breast exams and Lord knows what else, conducted in the airport as we pass through security. I'm all about multi-tasking. I wonder if they can check my cholesterol and this eye tic I develop when I read articles about TSA. At least maybe I'll go from 'Female Random!' and pat down before I even hit the scanners to not having to schedule a physical in the doctors office ever again.  "Excuse me Officer, does this feel weird to you? I feel like it might be something."

Rachel, you owe my employer a new keyboard - one without cheap dark roast coffee sputtered all over it.

But I think you're on to something. Maybe the TSA can check us for fever, test us for strep throat, and prevent pandemic by giving us our annual flu jab.  They can assess our exposure to hazardous chemicals like nitrates.  They can distribute Eddie Eagle firearm safety brochures.  They can teach our kids not to run with scissors, especially on the jet way.  Weight Watchers can track our height, weight, and body mass index throughout the travel year.  Abdominal X-rays to check for explosives carried "drug mule-style" would require a pregnancy test for female suspects - no charge of course. Lens Crafters can modify retina scanners to provide eye exams. The American Cancer Society can buy signage rights where the breast exams and prostate palpations are performed. Gold's Gym can measure the pulse, respiration rate, and flexibility of travelers as they do the TSA "coats-shoes-belt" drill. Dr. Scholl's can size us for orthotics by evaluating our postures in stocking feet. The ever perky Denise Austin can brand a TSA 3-1-1 workout video.  

Just think of it, nationalized health care that contributes to the global war on terror while turning a tidy profit!  Yes indeed, it's clear we've all been looking at this the wrong way...

This and That

From some of the discussion groups I frequent...

"Does anyone have a report or know of a study that has been conducted that indicates whether or not a newly-constructed homeless shelter increased crime or risk within a geographic area? A residential community or commercial center?"

A quick Google of the terms homeless shelter effect on "crime rate" pdf returned some papers such as:





Some are academic, others are position papers written by organizations with an obvious stake in outcomes. I don't have time to assess them for bias and agenda. Perhaps you can let us know what you find in the course of your research on this important topic.

"I'm searching for a template or developed scenario to conduct a response exercise/drill on purposeful food contamination in the retail convenience store sector."

You might try a replay of the 1984 Rajneeshee bioterror attack.


UPDATE: Another poster suggested DHS/FEMA National Planning Scenario 13: Biological Attack – Food Contamination


And CARVER + Shock.


Not cheerful stuff...

"Interested in CPTED guidelines. Any CPP out there currently working with CPTED principles?"

There is a CPTED group at LinkedIn managed by Severin Sorenson, one of the top people in the field. He has a website with resources too.

Anything by Randall Atlas is worth reading.  His website is here.

Likewise Crime Prevention Through Environmental Design by the late Timothy Crowe is a classic in the field http://www.amazon.com/Prevention-Through-Environmental-Design-Second/dp/075067198X

In the mean time just in case you haven't read Creating Defensible Space your reference library is incomplete.

The wikipedia external links on the topic lead us to a very interesting annotated bibliography http://www.thecptedpage.wsu.edu/Resources.html

Fifty Years Since Freedom Seven

I'd be remiss if I didn't tip my hat to the memory of Alan Shepard's historic sub-orbital flight...


The anniversary has been written up by many people who actually remember it. I was three years old.  I became aware of the space program during the Gemini missions and came of age during Apollo.  One summer in the late 60s my Aunt Phyllis drove me to Casselton, North Dakota, to see a mock-up of the Mercury capsule.  I patiently waited my turn to sit in the capsule.  It was not roomy, even for a kid.  I had to be gently encouraged to exit when my time was up.  I went to the back of the line to wait for another turn.  Tom Wolfe did a nice job of the retelling the story of the Mercury Seven in his book The Right Stuff. The movie of the same name is worth watching again if you haven't seen it in a while,  Alan Shepard traveled to moon as the commander of Apollo 14 in 1971.  He died in 1998. 

UPDATE: Some folks never realized that the Redstone used for the two sub-orbital flights was essentially a short range battlefield missile that relied heavily on the design of the WWII German V2 rocket designed by Werner von Braun.  The Atlas rocket used in the Mercury project's orbital missions, and the Titan booster used for all the Gemini missions, were originally intercontinental ballistic missiles designed to deliver Cold War nuclear weapons.  Neat article here.

Private Security Attitudes About The Role of Weapons in Preventing Workplace Violence II

The survey results are in...

image from photos8.com

Some recent discussions at the Security Source Online discussion group at LinkedIn got me thinking there may be some detectable demographic differences between security professionals who hold strong opinions regarding the role of armed security personnel and armed citizens in reducing homicides at work, in houses of worship, or at school.

I used Survey Monkey instead of LinkedIn Polls as there are people who were inviting to participate who may not have a LinkedIn account. I do not have a premium account at Survey Monkey so I was limited to ten questions.

Private security professionals at several LinkedIn groups, the management staff of a contract guarding company, line officers at a guarding contract client site, and three security-related blogs were asked to answer a brief survey at Survey Monkey titled “Private Security Attitudes about the Role of Weapons in Preventing Workplace Violence.” Five questions were asked. Three solicited opinions on the role of weapons in preventing or responding to workplace violence. Two questions assessed the knowledge of the magnitude and nature of the problem. Then five demographic questions were asked. This was a crude instrument and a very small, self-selected sample, but there were several results I find striking.

1) Homicides at work, in church, and at school in the U.S. have reached epidemic proportions.

24 answered True (42.9%)

29 answered False (51.8%)

Three answered “Other” (05.4%)

Comments:

“Epidemic is to strong a word. Worrysome is more accurate.”

“Epidemic too strong, but clearly homicides are too many”

“Don't know the data.”

2) Having armed guards on the premises will reduce the number of homicides at work, at church, or at school in the U.S.

29 replied True (51.8%)

22 replied False (39.3%)

Five replied “Other” (08.9%)

Comments:

“armed and well trained”

“uniformed presence/marked vehicles could reduce”

“They will but at what expense?”

“Some armed guards would help, but not all should be armed as this is not needed.”

“I believe having armed security will help in reducing the risk factor for homicides in the workplace versus not having them.”

3) Allowing employees, members of the congregation, school staff, or adult students to carry concealed firearms will reduce the number of homicides at work, at church, or at school in the U.S.

21 said True (37.5%)

29 said False (51.8%)

Six said “Other” (10.7%)

Comments:

“yes, with proper situational and firearms training”

“They will but at what expense?”

“Might decrease the number but not stop them.”

“depends upon their training”

“not sure, lets hear the evidence”

“Only professionals should carry, which train for those types of high risk workplace violence incidents.”

4) How many workplace violence murders occur each year in the U.S.?

For this question we rely on the Revisions to the 2009 Census of Fatal Occupational Injuries (CFOI) counts (2011) published by the U.S. Bureau of Labor Statistics. The numbers were revised on May 4, 2011. Prior to this adjustment the number for 2009 was 521. It has since been revised to 542.

25 respondents under-estimated, 57% (10-350).

Five (11%) responded saying the number was between 500-600. 521 was the correct answer; only one respondent was precisely correct.

14 respondents over-estimated, 32% (1000-3000, and one respondent said 40,000).

Comments:

“not sure”

“According to the BLS 2009 report there were 4,340 fatalities in the work place during 2009, with 521 by homicide. Although the BLS (1992 - 2009) report has shown a lessening of fatalities during this time, it should be remembered that medical science is saving ever more lives during this same time frame. To look ONLY at the # of Fatalities would be flawed. We must look at how many times someone TRIED to kill other humans in the work place, not just the # that actually died of their injuries.”

“Unk.”

“Approximately 1,000 murders occur, however there are more than one million workplace occurrences if you include incidents that do not result in murder.”

“Not sure, but I do know its out of control”

“Dont know”

“Unknown”

“Unknown”

“(which includes service workers killed in robberies, police officers killed in the line of duty, etc.)”

“Don't know.”

No respondent got this and the next question right.

5) What percentage of workplace violence murders in the U.S. are committed by co-workers, former co-workers, clients, family, or friends of the victim?

For this question we take our answer from Occupational homicides by selected characteristics, 1997-2009, published by the U.S. Bureau of Labor Statistics (2011). The correct answer is 24%.

37 said 70% (68.5%)

Six said 50% (11.1%)

Four selected the closest to the correct answer of 30% (7.4%)
 
Five said 10% (9.3%)

Two said “Other” (3.7%)

Comments:

“Again the BLS (1992-2009) report shows that although Fatalities dropped 50% from 1992 to 2008, they have only dropped 1% from 2008 - 2009 and again the BLS report only shows fatalities.”

“Don't know.”

No respondent got this and the former question right.

A) How long have you worked in the private security field?

Less than 10 24.1% 13

10-20 31.5% 17

20-30 27.8% 15

30-40 13.0% 07

More than 40 03.7% 02

B) What is your age and gender?

52 men and four women participated in the survey.

(Analysis of ages will be presented shortly.)

C) Education 

HS or GED 13.0% 07

Two Year Degree 13.0% 07

Four Year Degree 53.7% 29

Masters 16.7% 09

Doctorate 00.0% 00

Post doctorate 00.0% 00

Other 03.7% 02

D) I am or have been a law enforcement officer and/or a member of the armed services

True 63.0% 34

False 37.0% 20

Other 00.0% 00

E) Your politics

Democrat 18.5% 10

Independent 24.1% 13

Republican 38.9% 21

Libertarian 07.4% 04

Other 11.1% 06

Discussion

When asked the number of workplace violence murders committed each year in the U.S. 57% of respondents under-estimated. Only one in ten (9.6%) private security professionals correctly answered the question. 32% over-estimated the number. 15% of respondents did not know the answer.

When asked the percentage of workplace violence murders in the U.S. committed by co-workers, former co-workers, clients, family, or friends of the victim 10% of respondents underestimated. Only one in 12 (8.0%) private security professional correctly answered the question. Four out of five (83%) private security professionals over-estimated the percentage of workplace violence murders in the U.S. committed by co-workers, former co-workers, clients, family, or friends of the victim.

This has been explained by others who study the psychology of risk. We tend to overestimate the risk of encountering exotic hazards (airplane crashes) and downplay the frequency of more mundane hazards (car crashes).

Of the demographic traits collected none seemed to correlate with those in error or the few who got the right answers.

Opinion

As I mentioned in the introduction, this was a crude instrument. I am also no sort of statistician.  The survey represents very small, self-selected sample. The opinions expressed are just that, opinions. But two fact-based questions were asked. The idea that self-selected private security professionals with strong opinions about the risk of workplace violence were unable to accurately describe the magnitude or nature of lethal workplace violence is striking. This may be the result of lack of access to or awareness of the available statistics. Or it may be the consequence of the very human tendency to get it wrong when we conflate our feelings about risk with actually thinking about the real numbers.

UPDATED TO ADD: Some discussion group correspondents ignore cases that challenge what seems to be an article of faith...

"There is no time to waste as we saw in the Columbine and Virginia Tech slayings. Waiting for police response did no good to the countless victims."

Rather, as we saw at Columbine having a sheriff's deputy on site when the shooting started did the the countless victims no good. Why does everyone forget there was an armed school resource officer at Columbine that day? He exchanged gunfire with Harris without effect (his four pistol shots from 60 yards were misses), called for backup, and waited for it to arrive. Should he have been indoors instead of eating lunch in his squad car in the parking lot? Should he have entered the building to press home an attack on Dylan and Klebold? Should he have been better armed and better trained? Given that one cop with a pistol in the wrong spot was not enough to make a difference, how many appropriately armed and equipped personnel in the right spot would have been needed to stop the killing immediately?

Daniel in the Lion's Den

Or Dr. Steven Novella, M.D., on The Dr. Oz Show...


Doctor Oz officially endorses woo while Steven Novella does his best to speak on the merits of science-based medicine...you know, the kind everyone wants when they're really sick.  It was an uneven contest of course, but maybe Dr. Novella (who really should have chosen a coloured shirt and a more complimentary tie) got through to someone who will benefit from real medicine.  Dr. Novella is the President of the New England Skeptical Society and the host of The Skeptic's Guide to the Universe and The Skeptic's Guide 5 x 5.  He blogs prodigiously at Neurologica and Science Based Medicine.  Dr. Novella has offered Doctor Oz a opportunity to be interviewed for the SGU podcast and - unlike the conditions on The Dr. Oz Show - to have his entire unedited interview made available to the public.  We'll see if Oz takes the SGU up on its offer.

I've been thinking on which books would make good texts for a course on critical thinking.  I come up with three straight away:


In the mean time another excellent podcast dealing with SCAM - Supplements, Complimentary, and Alternative Medicine - is Dr. Mark Crislip's Quackcast.

Remember, it's effective and it's safe, it's not alternative medicine, it's just medicine.
