That sounds a bit disconcerting. I've discussed things like how to beat airport security, plant bombs to do the most damage, and in general ways to circumvent security measures. It's simply an intellectual curiosity, one even necessary to make things safe, and protect against those who think the same, but with intent of causing harm.

If the discussion alone is the damning part, with disregard to the intent... coupled with some prejudice, and add irrational fear.

Self censorship is what you get.
