It only takes on sensible juror and the cop goes free as he should.
The Left would view this as a win-win scenario.
If he is convicted, they get an innocent police scalp. If he is acquitted, they get to have more riots, which is what they want.
Hell, he could be convicted, and they would get even more riots because both cops weren't put to death immediately.
Drunk driving arrests are a scam so lawyers can get rich. If you ended them now and just put drunks in cabs or drove them home. The attorneys would revolt. Charge $10,000 fine instead of jail.
