I think the middle east already knows. If anything O'keefe's video will make terrorist overconfident and they won't try to disquise themselves.
I think O'keefe is on the right track. Embarrass the government. Instead of warning that terrorists could use the open border, as we have done for 6 years. Show people just how ridiculously easy it is. O'keefe does what unnamed sources cannot. He shows a video of Osama crossing the border.
Isn’t this stunt out of the Alinsky’s Rules For Radicals playbook? Mockery comes to mind.
