Just to be sure I got this right, the OSP officer stated:

He’s intoxicated.
He’s been drinking, so he shouldn’t be driving away from here.

West doesn't fare well on his field test, but they don't check his breath - even though they smell alcohol. 
They give him a ride home and leave his car overnight for him.

If anybody else had been EPD West they would have been given the breathalyzer, cuffed, booked, car towed, license suspension, fines....the whole 9 yards. It's one thing for local PD's to be dysfunctional - but you expect better from the State Police.
