The ProleWiki article takes issue with the official narrative that Webb committed suicide, claiming that "he [Webb] was assassinated in 2004" and citing the "multiple bullet wounds [to the head]" as evidence
The problem with this is that it is entirely possible to survive a gunshot to the head, and given the bullet trajectory, it doesn't really surprise me that he did survive the first bullet. The Los Angeles Times article (which the ProleWiki article cites as a source for the "multiple bullet wounds" claim) has this to say:
"When he pulled the trigger, the bullet sliced down through his face, exiting at his left cheek, a non-fatal wound. He pulled the trigger again. The second shot, coroner's investigators believe, nicked an artery. His body was found the following day."
This doesn't mean that Webb wasn't assassinated, but 1) the fact that there were multiple bullet wounds shouldn't be presented as evidence that he didn't commit suicide, and 2) extraordinary claims require extraordinary evidence
Unless more evidence is presented, I think the article should be modified to reflect this information
