Depends upon what he considers to be a 'gun crime'. If it's for a paperwork error, or a citizen having access to suppressors or other such garbage laws, then it's a darn good thing.
If he's talking about a gang-banger shooting folks, that's not really something he deals with. He works for a tax agency. A tax agency, btw, that has as it's main focus, the destruction of the 2nd amendment. So yeah, questioning his status as a decent citizen is appropriate. Gotta wonder how many citizens he's thrown into the gulag for making a mistake on a form.
Sounds okay to me.
