Years ago I read of one of the New Yorkers who “failed” to turn in his semiautos. Seems he had moved to Idaho or Montana less than a year prior to the confiscation edict, so the notice was forwarded to his new home. Flush with exultation at living in comparative freedom in his new home, he sent back a letter telling the NY authorities what they could go do. (Which apparently did include the taunt “You want ‘em? Come and get ‘em!”)
A few weeks later he got a call from his parents that his former home had been stormed by the NY police.

Thanks for the info. that fits with what I read about the NYC gun gestapo's response at the time.
