So, let's see - you won't believe what the government says - they can't be truthful. You won't believe what a group that has nothing to gain by lying about it says - they can't be truthful.
Basically, you will only believe conspiracy theories from groups that have no actual knowledge of the events.
Got it - you're a conspiracy theory supporter.
Yes, you are making conclusions. You are concluding that both the government and al-Qaeda have conspired to support a "lie" that Osama bin Laden was killed. You most certainly are making that conclusion by believing that both groups would have a reason to support the same "lie".
I guess that you don't believe the ex-Seal Team 6 members who have stated that they know exactly which one of the team shot bin Laden - they must be lying as well, right? There were 23 Team 6 members on that operation, and you apparently seem to have a low regard for the truthfulness of our US soldiers.
All of the top brass in the military must be liars as well. Those ten emails that were about bin Laden's burial must have been faked, or there must be a well organized conspiracy across multiple branches of the military, plus multiple branches of the government, and both Congressional parties. The Republicans must have decided to keep Obama's secret while they were trying to get Romney elected as well.
That sounds more plausible to you than Obama actually managed to kill Osama, right?
