Guy who ran over robber 3 times now charged with murder

This isn't even close. Defense of others went away after the guy ran down the street. If I was a judge, I would find the guy guilty and then probably cut him a break on the sentencing. But not too much, vigilantes are not allowed. For good reason.

What if the guy in the Tahoe accidentally ran over somebody else because he lost his cool and decided to run this guy down?
