The TSA has stopped zero terrorists. It's security theater. It's just dumb. No other country requires people to take off their shoes. No other country will feel you up if you fail the millimeter wave scan. Their false positive rate is so high it's pretty much random chance.
Sure security is bad in other countries. I've had to remove everything from my bag in several airports, but America is still somehow the worst in spite of that. Fuck the TSA. When I do leave the US, I take a train to Canada and fly from there. Their security is mostly the same, but at least I feel like I can't complain since it's not my country.
