In today’s US Gun Terrorism news so far:

The Denver Post:

One Douglas County deputy died and four more were wounded along with two civilians Sunday morning at a Highlands Ranch apartment complex. The shooter was also shot and is believed dead, the Sheriff’s Office said in a tweet at 9:32 a.m.

Deputies were responding to a domestic disturbance call.

CBS News:

Police in Houston say they arrested a man found with guns and ammunition in his hotel room early Sunday, as authorities across the country remain on high alert ahead of planned New Year’s Eve celebrations.

The guy was drunk and tottering around hassling other guests, so police asked him to go to his room and when he refused they escorted him there preparatory to escorting him with his belongings out of the hotel.

When officers arrived at his room, they found “several” firearms and rounds of ammunition in the room. Cintillas said there were “several” firearms but “not a huge amount.”

The man was taken into custody. Police would not comment on the exact type of firearms nor on why the suspect had the weapons and ammunition in his room. Cintillas said the officers’ intervention “averted a potentially bad situation.”

And it’s not even afternoon yet.
