In theory, it is. In practice, prosecutors are very reluctant to go after cops for such type of crimes, or for any others that relate to their professional functions - perjury, excessive force, evidence tampering, violating disclosure rules, unlawful searches, etc. Plus, there's qualified immunity thing, which makes it very hard to gain a successful conviction even if the prosecutor is willing. It'll take a big SCOTUS decision dismantling that construct to start seeing any change there, and that may take a long while to happen.
