The abuser did not show up for the protection order hearing. Can his/her gun still be taken away?
Maybe. The abuser does not have to come to the hearing in order for the law to apply to him/her, but s/he does have to be given notice of the hearing and an opportunity to attend.1
If no hearing is scheduled, and/or no notice is given about the court hearing, then the federal firearm law might not apply to the abuser.2
