You seem to not understand how a police report works. They are not alleging in the report that he is guilty of an offense. They must title the report something, so they put the title of the charge it would be if an offense was committed.
For example, if I come on the scene and you say a guy robbed you, and the guy says he didn’t, and there’s no evidence either way, I’m making out a report for “Robbery”. That doesn’t mean I’ve charged anyone or intend to charge anyone.
that was my thinking, too.
