Too many people simply do not understand what "freedom of speech" is.

The only "crime" that the pastor could have committed by burning a Koran would come from not having a burning permit, if that was required. Also, if the book did not belong to him and he did not have permission to burn it.

The pastor committed a violent act against a pile of cellulose, nothing more. To commit violent acts against people (murder!) in response is an insane act by brainwashed thugs.
