Not sure what bodycam video some of you guys are watching, but he looks pretty buzzed to me. I defended at least 200 of such cases over 30+ years, and it doesn't take very long at all to get to a 0.08 BAC...in other words, you don't have to be stumbling drunk. In the event of a breathalyzer test refusal (which triggers an automatic license suspension in Wisconsin and any others with whom that state which may share driver information), officers can still proceed with an arrest based on other evidence (odor of alcohol, physical appearance, failure of field sobriety tests, etc.). As for the handcuffs, that's SOP...no matter who you are.
For a guy in Tony's position, with the means to easily arrange for alternate transportation after time spent at the 19th-hole or wherever, there really isn't any excuse for getting behind the wheel. Very unfortunate mistake; we've all made them in life.
He's entitled to a presumption of innocence, and we'll see where the case goes? He'll certainly have first-rate representation. Just glad no accident was involved.
