I'm protecting you here. Even if you are a broken record, you do not need to fall into the same pattern as the degenerates here at the first sign of violence look for anything brown. Stop that, use your analytical and skeptical side of your brain for a change.
What is the profile of a vehicle jumping a curb into a sidewalk? It could have been a great number of things.
As it stands now, a beer delivery truck, or a truck delivering something to a brewery, was stolen and it crashed into people. It's possible that the driver panicked and lost control of the vehicle, was otherwise incapacitated, or was incapable of handling the truck via inexperience. It is also possible he stole the truck with the intent to cause harm. Killing only 4 if that is the case is a really bad job of that. So I'd argue that somebody has a problem if they are equating anything remotely resembling an act of violence and that they were likely brown. I've never been one of those people to jump to those kind of conclusions. All people, including brown people, deserve the benefit of the doubt.
