He was a US citizen, which was why he was allowed to enter the US.
I understand, but did you read what he was carrying with him? And he was wearing a blood-stained sweat shirt. C'mon, its not rocket science. "No crime lab" WTF is that? They need to promote some Wal-Mart employees to work the border check points I guess. Just look at the guy's pic, he's got psycho eyes.
