Is osama bin laden dead?

I was reading on another post comment about how they never showed proof that Bin Laden was dead and how seal team six that killed him all died in a helicopter soon after. Well I googled it and it seems like that is what happened. It was not a common event either. The helicopter being shot down was the biggest single loss of life in the history of the Seals. In fact more Seals died in that one mission than in all the missions in Seals history combined. It does seem at least a little suspicious.

There is a lot of bad information on the internet so if I am missing something or getting bad information, please let me know. But please don't just say it is a crazy conspiracy theory. It might be, I don't know, but give me facts to support that it is. We all know the government's official account, so just saying that if the government says it, it must be true, adds nothing to the conversation.
