I remember reading of a man years ago, whose house was raided by local police. He had a legal licensed and taxed mint condition Thompson Sub-machine gun in his collection.
After several years of legal work, he got his rifle back. It was so rusted up it no longer was useful. It looked as if the police had sprayed it down every day with salt water.
Reminds me of how the British in South Africa, in the mid 1800s confiscated all the legal owned muskets of the natives. After finally getting them returned, all were so damaged as to be unusable.
That’s what they do..................
