Don't they make a big deal about claiming credit for what they do? In fact don't they try to claim credit even for things they didn't do, like the big blackout? Or are they suspected of that in reality? I wouldn't be surprised if they are behind the fires. I wouldn't be surprised if they say they are but the government says they aren't. Who should be beleived in that case?
Either that or Al-Qaeda's American allies (aka the Democrats) will blame Bush.
There were FBI warnings several months before the blackout that they could attack the power grids. When the blackout occured and they did take credit, no one believed them anyway. Then there were the blackouts in London and Italy shortly after that.... but none since. Sorry, but I have a hard time dealing with all of these coincidences. I know stuff happens, but we are at war and I believe that at this point they will use whatever means they can.
