I’m not too sue the officers were WHOLLY unreasonable. BUT!! It takes about ten minutes to get a judge to issue a telephonic search warrant. They should have done that. It’s in the Constitution. Duh! Could have been done on the way to the scene.
And the professional police officers didn’t even try to get a warrant.
It’s possible that they just thought they could get away with becoming criminals.
It’s also possible that they knew a judge would NOT grant them a warrant.
I hold professional armed agents of the State to a very high standard. If they can’t meet high standards, they need to find another line of work.
