So when you see a burglary in progress and you hold detain the criminals until the police arrive you are now committing a crime?
Arrested the wrong people. Probably FBI coached by Comey or McCabe, or Strok or Paige, or Ohr or hell, even the big 00000 himself. There it is.
If you are a convicted felon in possession of a firearm, yes that’s a crime. That’s why he was arrested.
