Yes..i have seen court paperwork (Judgement and Sentences)..where a person brandishes a weapon/firearm and doesn't use it...the victim calls law enforcement and the perpetrator is then sentenced and convicted of felony Assault 3rd..if you pull it, it seems as if you've got to use it...kind of funny to think about. If that guy were to call law enforcement ..get rid of the knife, tell a story about an argument you two had, tell them he was the victim...you get arrested searched..and most likely get convicted of a crime..if not.. you will have had to spend a lot of money on an attorney to get the case taken care of...a lot of money..probably in the $1,000's at least...court appointed attorneys will only get you the previously mentioned Assault 3rd..and yes I have seen it occur (on paper) multiple times...
