Non compliance to draconian gun laws is very high in NY, Ct and NJ. I would bet LEOs would be very leery about going door to door to confiscate weapons,
Besides, this poorly thought out plan is impossible to carry out.
There are not enough law enforcement personnel in the US to even begin to go door-to-door to confiscate guns from law-abiding citizens. Million of guns and not enough cops.
Stupid idea from a stupid candidate.
Dork. Go eat some more dirt.
