Again read your own statement:
"“So what? He was just a drunk. Arrest him tomorrow.”"
He was INITIALLY BEHIND THE WHEEL when the police arrived.
Right?
Hello?
He wasn't running anywhere, when the police arrived.
Right?
Unless you think he was sober when he arrived in the drive through, then got drunk on the spot...he DROVE AROUND DRUNK, as in DUI, then passed out DRUNK in his vehicle in PUBLIC...behind the wheel.
Got it?
You think the police should arrive, then STAND AROUND AND WAIT until the DRUNK wakes up? Then arrest him? You can't possibly think that's a reasonable thing to do.
Reckless, as I said.
Well said.
