Ben Carson is being condemned for recommending that people mob a shooter to stop the shooting.

Carson could be right on that point: fighting back, the crowd could limit the number of people that the shooter can kill. When the shooter's magazine is empty, the crowd will stop him from reloading.

It is a mistake to claim that that statement blames the victims. It isn't about blame at all — it is practical advice. As for the blame, that falls on the killer in any case.

I think this advice applies to many situations where people are subject unjustly to violence. Think of the Stonewall riot. Think of evictions.

The rest of what Carson said is mistaken.
