Body Scans, Pat Downs, the TSA

There is an easier way to check air passengers than with group body scans and pat downs.
I will not give you a lot of mumble jumble so here it goes.

1. Let each airline handle their passenger search.
2. Allow airlines to opt out of searches- but have passengers sign a form freeing the airlines from any liability.
3. Most reservations are made weeks or months in advance. This should give the airlines and the TSA plenty of time to check out passengers.
Any day of flights should be body scanned and patted down.
Any passengers during the investigation prior to the flights that appear suspicious should be double checked the day of flight.

Anyone from areas of the world that have terrorist ties will be double checked.
Any suspicious passenger who refuses to be checked will not fly.
