This is a perfect example of why social media is a total disaster and no one should be trusting it for anything at all. There are many, many things that seem to be taken as fact on social media that are impossible to find on any reputable media source. Maybe the crowd was chanting hang Mike Pence, maybe not. I'll wait until a credible source reports it. The AP had reporters in the crowd (getting assaulted [1]), presumably many other organizations did as well, I expect them to report what they heard.

There are many other examples (both from this incident and others) already prevalent, including on HN, which is really depressing.
