The main problem here is that most of those guys are probably ex-military. In Iraq, they where used to do anything. None of the brutality gets reported by US news anyway.
But now that they're in the police force, they think that their own citizens deserve the same treatment as an Al-Quaeda operative.
There's something seriously wrong with this statement.
An Al Quaeda operative? The US military do not terrorise Al Quaeda operatives. They terrorise innocent families in Iraq and Afghanistan the same as they apparently do in the US, it's just in Iraq and Afghanistan nobody can stop them because their government says it's okay and nobody with any power gives a shit about it. I find it much easier to believe that these guys were brutalising (killing?) working citizens, women and kids in Iraq (or wherever) than that they were genuinely infiltrating Al Quaeda.
And before we get any "oh i'm sure our troops are doing a good job" rubbish, yeah, i'm sure they are, most of them, but that doesn't mean they've got any clue, as a foreign army, how to infiltrate a resourceful, indigenous operation like Al Quaeda's supposed to be. Their hearts can all be in the right place and it doesn't mean we're closer to ending the Al Quaeda "threat". It just means thugs have got an outlet for the brutality that evolution has encouraged in our species.
