Because it's my duty as an American citizen to be on the other side, rifle in hand.
Let me explain who the "other side" is. It is terrorists, abroad and homegrown.
There is a much bigger threat than most people know about.
Law Enforcement has been receiving the FBI's bulletins for years now. I've read every single one of them, and frankly some of it is pretty alarming. There are instructions on each sheet that the info is not to be disseminated to anyone besides L.E.
They contain local, national, and international news and information from covert informants. A lot of this stuff would scare the crap out of the general public. Some of it is very general, and some is precisely specific. The fact is that the FBI does not want to start a panic amongst the citizens of this country. I guess you could call it a need to know basis.
L.E. is considered the first line of defense against terrorist activity in the USA. There have been many things that street Officers have already thwarted, and the FBI feels that it will be street Cops that have the most chance of encountering/shutting down terrorist activity.
If you think that the war on terror is a made up fantasy, I can assure you that it is quite real. Be glad you don't know what I know!
