CNN is reporting three dead – probably including the gunman – in a mall in Columbia Maryland this morning. “Howard County Police Chief Bill McMahon told reporters that the shooter apparently shot two people before shooting himself in a store on the second floor. The motive was unclear.” Do we really have to check the mall’s policy on concealed weapons? No, no we don’t. This is Maryland, after all. “A federal official briefed on the shooting told CNN preliminary information indicates the shooting may have been related to a domestic dispute.” So this probably wasn’t a random spree killer, though it’s likely to be portrayed that way since it happened in a public venue. More to come as the picture emerges.
