It's not complicated at all. They executed a search on false accusations. If they were to get a search warrant from the courts for some type of crime that would be different. But a search based on someone swatting him is complete bullstuff and should be thrown out the second a judge lays eyes on the charge.
it's actually primarily to prevent police corruption by letting them go in one false cause for one thing and miraculously finding what they were looking to charge the person with to begin with, but didn't have any evidence for.
