In most states, not without a conviction.<quoted text>
Wrong dumbass! When a grand jury issues an indictment and a judge issues an arrest warrant in a case when the suspect has made violent threats sufficient cause has been made to deny that person the right to possess any firearms. In the case of this individual a single shot .22 rifle would be considered an illegal firearm.
You're an idiot!
Due process still applies, despite Obama's desire to be judge, jury, and executioner.
