What do you mean by someone fleeing in a vehicle? They seem to have quite deliberately run people over in a terror style attack.
It seems like quite the coincidence, I guess instead of extremist clerics and infidels we now have talking heads on the news banging on about dubious claims of “white supremacy” in relation to this case and a back drop of scapegoating white people for everything (this case has been cited as an example of “white privilege” for example).
When you’re allowed to demonise a group of people continually then don’t be too surprised if some act on it. It’s not the same background or as extreme as say 1930s Germany, that was a minority rather than the majority and the rhetoric ramped up to 11… But if you do carry on with conspiracies whereby group X has special privileges, everything that’s wrong about society is down to that group etc.. that can drive hatred.
This incident does seem to have been the result of some crazy BLM supporter (he’s been identified, social media posts discovered) and quite plausibly deliberate.
