Depends on why. If the suspect was found or pled guilty, generally he loses the gun.
so the gun belongs now, to the Memphis PD....who sells it to retailers who sell it to you or me or to a dirtbag.....legally just like any new or used gun...(or perhaps ..to a paper buyer who supplies dirt bags with weapons)...what I am saying is that if a dirtbag is going to commit a crime with a gun, he is going to commit a crime with a gun and where the gun was 2 years before does not matter.
