Not only does opening bags increase the probability of a crime of opportunity, as GradGirl states, but it also is extremely un-American.
OK. Fair enough. We are truly in agreement. When I said no such thing as "too many searches," I meant based on sound security principles. Of course, I agree with you that bags shouldn't be opened just for the heck of it to see what "goodies" are packed inside.
