lets say barry gets stabbed in the neck because sure, the secret service is around but can't get there in time.
"well, south africa should have vetted him, not the secret service's fault"
no, that's completely unacceptable. this was a dangerous man who got off of a murder rap because he's a schizo. he's a known violent schizo. and he gets to stand next to the president of the us
it's not like he was some random guy. when the georgian tried to kill bush a few years ago, luck saved the president. but he was some random guy in the crowd. this guy was given clearance to stand next to various heads of state. he didn't even know how to do sign language
