According to the linked report, at least, the process to clear the 212 3B (and the no-fly list designation) started once the feds spoke to the guy and he was no longer considered a person of interest in the bombing.
I’m so very sorry to tell you this, but to get a real understanding of all the mechanics of this story, you would have to go listen to Beck’s broadcasts or go read it over at the blaze. It is not a simple matter of just saying, oh, he’s not a threat - the point is that there was already a file on him, before the marathon happened. That file was altered.
They already knew who he was before he ever got to the hospital. The records were altered, that is story, in part.
Yeah! After one conversation..lol. I will say, your not the only one here on the payroll.
