We are not safer because we take off our shoes, clothes or whatever. The TSA has prevented ZERO terrorist attacks or potential hijacks since they were instituted. Keep your shoes on and refuse to be groped or shot with X-rays. It doesn't make a difference. You can absolutely band all guns, bullets and violent movies and games and it will NOT make a difference. For useful instructions please take a look at what happened in Australia after they banned all guns. Crime literally exploded because criminals now know they do not have to worry about victims possibly being armed.
