I read a nice comment about conspiracy theorists that explains the true believers. Aside from "they're crazy", what it is really about is simple validation. "I"m so much smarter than everyone else that I figured this out within four seconds of hearing it on the news, look at me I'm so smart. I pity all these stupid people who don't see the truth." Look at everything they ever post and you will find that statement in there somewhere. Usually something like "well, myself and other critical thinkers know that blah blah and if you can't see that you are simple-minded sheeple and I feel sorry for you."
Of course, the exact same method is a pretty effective troll, too. The "I'm smart you are dumb" line is just terrific bait.
They are truly sad and pathetic.
Also, when the innocent brothers found out they were the suspects, they just happened to stumble upon a cache of guns and home made explosives. They panicked, it happens. Perhaps the arsenal was planted there and when they discovered it they felt they had no choice but grab what they could and start lobbing bombs at the police. Or maybe the entire police force was in on the gig and used hollywood effects to simulate explosions, and the "injured" police was all actors or self-inflicted wounds. As you dig deeper and deeper it all just seems more and more likely. WAKE UP SHEEPLE.
PS: Bush used explosives to blow up tower 7, the one that no planes hit, because he figured that wouldn't look strange at all and would be easily explained to any layman should they question it. Only blowing up the big towers that the planes hit just wouldn't have been good enough to make people hate muslims and Saddam Hussein. Also, the use of Saudi nationals backed by terrorists from Pakistan and Afghanistan to trick us into supporting a war against Iraq (wtf?) was the master stroke of the plan.
