Like I said, I think that the system needs to be increased across the board.
But it's also painstakingly clear that there is a better chance that someone who is a Muslim/Arab is more likely to blow up the plane than the 85-year-old white grandma, so we shouldn't be blind to that either. Not saying don't check them both - wouldn't be prudent at this juncture - just saying to use your head.
Certainly, I would agree that the grandma is less likely to be a terrorist, but I also think that the overwhelming majority of young Arab or Muslim males travelling on airlines is doing so for work or pleasure. Fortunately, without racial profiling we haven't had a commercial flight blown up since 9/11 (knock on wood). I think that because of the security measures implemented after the attacks, we have deterred, if not thwarted, some attempts at terror. I honestly don't fly much and don't know enough about the airline industry to suggest what more can be done to maintain and improve vigilance.
