From what I understand, somehow, someone in British intelligence infiltrated a cell and reported on the goings on as they were preparing to do a dry run with this. If this is actually the way it was done, that was a coup in the intel world as getting infiltration into a terror cell has not been easy at all. As far as I know, this is the first time a Middle Eastern type terror cell has been infiltrated.
I flew yesterday from Burbank to Denver and back. The security on domestic flights was pretty tight, and there was plenty of additional screening by TSA and a good presence of law enforcement. Was it over-reaction? Maybe, but in cases such as these, I would rather be a little inconvenienced than dead. Everyone else that I was around were patient with it as well. You have to adjust. I wasn't afraid, as that is what the bastards want. I actually felt safer knowing that the checks were quite thorough, and I was watching things closely myself and remaining vigilant.
