The "shooting them" was because they shot a black man with a tazer for simply wanting to retreat to his own house.
Besides the fact that I disagree with the way Taser (it's an acronym, there's no 'z') was deployed in that incident, it wasn't down to him "simply retreating to his own house". There's also no evidence that him being black had anything to do with the way he was dealt with.
You scream "logic" every 5 minutes yet you're only ever interested in your own rather peculiar brand of it.
