The odds are that the officers involved likely have committed more crimes than their victim.
No crime was committed, therefore, the money was not theirs to take.
Police today are taking a page out of the Sheriff of Nottingham’s playbook.
We don't know the money was not acquired illegally, so we don't know no crime was committed.
We do, however, know the police have produced no evidence of a crime, and that's the relevant point.
BTW, I've heard of this policy being used to confiscate multi-million dollar yachts because a guest or crew member, unknown to the captain and owner, had a small amount of drugs on them.
