It'd be funny. . . except what probably really happened is he politely informed the officers he had to urinate several times. The officers probably continually said some dumb ass shyt like, "You should have thought about that before you committed a crime." Then to feel better about their miserable lives that necessitates torturous displays of power, they denied him use of the restroom to the point of him being forced to urinate himself,
rather than choosing to put his health at risk by holding his bladder.
It says he blew a 0.09. That's buzzed. That's not piss yourself wasted.
And while I'm here... immediately plead the 5th. Don't consent to any searches. Refer matters to your attorney. Crack the window. Don't make eye contact with officers because they will accuse you of looking drunk, even if you're stone cold sober. Refuse the breathalyzer and field sobriety tests.
