You don't have to GO UP AGAINST people. You SERVE THEM SEARCH WARRENTS, like we used to do. You go to their door, with a warrant (and perhaps a bullet resistant shield, if you really feel you need to), and you let them know they must comply with a search warrant.
Only upon refusal do you employ 'shock and awe'. No-knocks with military tactics like these are BULLS***. People CANNOT KNOW these are cops, and HAVE EVERY RIGHT to defend themselves against armed invaders!!!!!!
"Tucson is notorious for home invasions and we didn't want to look like that," said Lt. Michael O'Connor of the Pima County Sheriff's Department. "We went lights and sirens and we absolutely did not do a 'no-knock' warrant."
Not that you'll buy it.
