As I understand things, traffic tickets are generally revenue to the police, so they do care if you win your case. They&#x27;ll only really notice if large numbers of people start doing this, but a principle that their unsupported word is no better than yours will certainly rise to that level.<p>There are a lot of process reasons to give the police the legal right to overswear civilians. They basically boil down to the same problem discussed in the Volokh piece, which is that without that right they lose the ability to prosecute (I&#x27;m not claiming they are prosecutors; I want to use that word in a more general sense) most of the cases that are meant to be their job.<p>But this isn&#x27;t compatible with the much-vaunted notion of &quot;innocent until proven guilty&quot;; it&#x27;s actually a judgment that most innocent people should discover that it&#x27;s impossible to be found innocent once they&#x27;re charged.
