Part of what stops police from routinely infringing civil rights in the pursuit of justice is the legal doctrine that evidence obtained illegally is inadmissible, as is all evidence gained from further (lawful) investigation based on that evidence [1]. what is needed is a law that operates in a similar way, that states that in any lawsuit or complaint against the police, there is a presumption of guilt on the part of the police officer in the event of &#x27;malfunction&#x27; of monitoring devices. The only way to make the police comply is to make it in their self-interest (or at least in the interests of the city that would regularly have to pay out presumptive damages) to make sure they are working.<p>[1] <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Fruit_of_the_poisonous_tree" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Fruit_of_the_poisonous_tree</a><p>Edit: typo
