I like many greatly dislike the TSA, I understand they have a job to do I just don't like they way they do it, reacting to threats, violating people, treating us like cattle. (I will be opting out on Wed, again)

So instead of complaining more I thought I would try and think of a proactive solution to the problem and this is what I came up with.

Step one – background check on traveler - this is currently done as the TSA requires full name and DOB of passenger. The airlines submits this info to the DHS for checks prior to flights.
Expand this portion to include a threat assessment level. Base this on life events and stability, is there a criminal record? On the cover does this person pose a threat. Do they have a family, do they have something to live for? Are they travelling alone, with family, or coworkers, are they US citizens?
Cross reference this info with the persons travelling history on airlines. Are they a frequent traveler? Have there been incidents onboard aircraft in the past?
This is a simple version that could create a treat level based on the person and their behaviours.

This threat level could be placed on a boarding pass in the form of a bar code or some other difficult for the public to read code.

Step two – Behavior profiling, Add TSA agents at the beginning of screening. These clerks will do the id check, verify the threat level via boarding pass code, verify that it is a legit boarding pass. Essentially cross ref the database to the traveler. They will also question passenger as to where they are going, why, and ask other questions as to the reason for travel. Customs at every country does this upon entry. Based on the threat level and behavior of the passenger a level of screening will be done. A guy that is about to try and kill himself and others probably will be a bit nervous.

Step three – today the threat is bombs, for an added level of security dogs will be used as needed as well as the bomb sniffing machines.

End the liquid ban, end the shoe ban

So the frequent traveler with the low threat level will be subject to the metal detector, and the standard x-ray of carry on materials. Cause an alarm and you go to secondary screening.

Higher threat levels justify higher security measures. All the way up to the ATI and “enhanced “patdown

Will it be expensive? Yea, but not anymore than the 1000’s of ati’s that the TSA is buying.

Would it be a comprehensive and proactive approach to judge a possible treat and act accordingly instead of the current policy of everyone is a terrorist until the TSA proves you’re not? YES

The vast majority of travelers are not a threat and would pass through the metal detector and standard baggage x-ray screening.
