32-year-old Heather Heyer killed after car crashes into crowd in Charlottesville Va. during White Nationalist demonstration (who were the only ones permitted to demonstrate)

I wasn't there, so I don't profess to know what happened, but.....Aside from"white supremacists", neo-nazis, black lives matter, antifa and possible other extremist groups were there,....As dangerous as she should have known it could be.....WHAT WAS HEATHER HEYER DOING THERE ??
