You’re a moron.
You really need to read up on the facts of the case. It was NOT a no-knock warrant. It was NOT the middle of the night. It was a VALID search warrant. He THREATENED them with an assault rifle. A tragedy to be sure. And maybe the warrant was obtained on shaky grounds, but the SWAT unit serving the warrant didn’t know that. Beyond the validity of the warrant, SWAT had been briefed that Guerena was considered armed and dangerous. I think the whole thing stinks but the SWAT officers at the door were rightfully defending themselves.
