Ever been arrested? Sure seems like a punishment to me. There are consequences for run ins with law enforcement. Being placed in a state of detention is one of them. Even if you aren't formally charged with a crime you were punished by being detained by police. Presumption of innocence doesn't supersede probable cause.
But being arrested isn't a punishment, because you're still presumed innocent.
