Security Screening
Thanks for the comment Christep.
You are correct with regards box cutters, which were said to be okay at Logan.
My info & my experience is that what is /is not an approved carry on item varied from airport to airport, and the company contracted to do the screening.
Regardless of this point, what the proponents of a comprehensive CAPPS are pointing out is that such a system would have put up no less than four red flags on each of the hijackers. When you have five pax with highjacker profiles being thoroughly screened and each carries a potential weapon ,is it not likely that this would have raised the alarm?
Initially, the CAPPS was capable of being comprehensive but the White House Commisssion on Aviation Safety & Security ( Report Feb 12 1997) found that a system using racial profiling is discriminatory.
The key terrorist profiling indicators of race,gender,nationality etc were not allowed to be used.
