I don't know. I just found out from reading the thread that they'd done a controlled buy from the guy (so now we definitely know he was dealing.) Maybe he'd bragged about "I'll shoot the cops if they ever come for me" or some such. Who knows?
Maybe they wanted to try out a new tactic (maybe some new room clearing technique or something like that) in what they thought would be a *low* threat raid. Who knows?
Like I said earlier, I think I would've been more tempted to snag him in the parking lot right as he left work, but that's just me.
This has gotten a lot of radio attention down here.
Your tag line says it all, and too many of you threaten it.
