There is! Jury nullification. "Yeah he's guilty but we're judging the law and its application as dumb and find him innocent" it used to be championed by old-school lefties as a way to beat the tyranny of the state, funny enough. Worth mentioning that it's entirely legal, but illegal to bring up in a courtroom. Darrell Brooks aka "Grounz" even mentioned it during his closing statement.
