I have been wondering this for years, and I agree completely. They might as well run around with no armor.
"They'll hunt me; They'll condemn me; Set the dogs on me; Because that's what needs to happen. Because sometimes, the truth isn't good enough. Sometimes, people deserve more. Sometimes, people deserve to have their faith rewarded. Not because they want to, not because of chance, but because they deserve to."
