Earlier quoted context omitted.
Excluding the evidence would incentivize police to stop choosing the most convenient interpretation of the law. They should have to try to make the most accurate interpretation, which means punishment when they are wrong. Just like for everyone else
No. In 2020 the police went to a magistrate judge to ask for a warrant. The judge issued the warrant. Five years later, another judge has determined that the warrant should not have been issued in the first place. That is not the fault of the police, and there is no reason to punish them for it.
It's not punishing the police. It's not allowing them to use evidence that they shouldn't have been allowed to gather.
Fining them, firing them, and/or jailing them for breaking the law; those would be ways of punishing them. That's not what is being discussed here. Admittedly, we pretty much _never_ punish police no matter what they do, so it's kind of a moot point.
