I find it odd that there are people who feel more safe when they take off their shoes. Whenever I've gone somewhere where they pat me down and check me with a metal detector wand, it makes me feel like someone is going to shoot me inside there. I feel more vulnerable.
I recently went to a rollerskating rink where I was wanded and patted down by a police officer. Of course he didn't even check my skates which has more than enough room for a hand gun. Metal detector and pat down at a skate rink, perhaps I shouldn't be here. Did I feel safe there? Not at all, it did the opposite.
