Speaking purely for myself, I have zero probs with a scan or a feel-up. The first, because I don't fly that much and so doubt the dreaded rays will do any more harm than my proximity to Hanford, and the second because it happens so seldom any more.
Seriously, I think flying, like driving, is not a 'right' but a privilege- and if you have nefarious plans to blow up my plane, I'd like your sorry ass to be busted beforehand. I'm not sure if the TSA's latest measures will be any more effective than prior ones, but something has to be better than nothing. It's a weird world we live in these days, and it's only going to get worse.
