@futurebird@justafrog I think it depends. I've not read enough on the incident (other than hearing the jokes) but cops do have a huge amount of discretion in charging someone.
A cop flustered by fame might not be as rigorous in enforcement.
I've had cops pass me through DUI check points when I said I had a drink on the ferry. Young, pretty white chick in business clothes, 7 pm in the evening, while they weren't treating people of color with nearly as much courtesy, demanding papers and what not. Seizing cars for any reason they could. Came out later that they were abusing the DUI process to collect fees. Show me your papers! Kind of thing.
I stopped trusting cops and DUI enforcement after that experience. I was by no means drunk, but I should have been tested if they gave a shit.
