So there was another crazy event at the Capitol on Friday and two people died. Earlier in the week, we had our third mass shooting in two weeks, this one in Los Angeles, in which four people died including a nine-year-old boy. We don’t yet know if the driver who smashed into a barricade at the Capitol and was shot after killing a Capitol Police officer had a clear motive, but the Los Angeles gunman was a cold, methodical killer.
