Police were called to my home in Mich on a domestic dispute (2012) The man involved lied to 5-0 and said that guns were involved,?

So because he discribed this imaginary gun, the police tore the home apart looking ( never found) because never existed. Now what they did find was a bag of weed with at least 2oz's in it, that the idiot involved in the D.D. his in a dresser drawer, The police took it and asked who's it was, obviously no one admitted to it because it was planted by the idiot. The police took the pot, never ticketed anyone with it or arrested anyone on it, but did arrest the idiot man on D.D., That happened in 2012 and now that its 2015 One of the arresting officers is trying to pin the pot on one of the Teens that resides in the home? But the official papers state, misdemeanor possession of marijuana? Anyone have any insight or advise on what can or will happen? T.Y.I.A.
