And since both are Lawyers you know they will sueSomeone has dropped a bollock here. Firearms cannot be confiscated without and until after due process.
Back in January or February of this year a Democrat State Senator, Jamilah Nasheed, introduced Missouri State Senate Bill 543 which would have suspended Second Amendment rights and allowed confiscation of legally held firearms without sufficient due process.
However the bill never made it out of committee and was binned. Therefore the seizure of any firearms by law enforcement was illegal. I see a nice fat cheque heading to this couples bank account sometime in the future.
