Behold the power of the Lautenburg amendment. “Reasonable, modest, common-sense” restrictions on the right to keep and bear arms. Something more than 40 years ago, that carries a smaller fine than a speeding ticket, prohibits someone from owning a gun for life. (At least, after the law was passed. And it was retroactive.)
I do think calling $1000 in 1968 money less than a speeding ticket is pushing it a bit—that would be well over $6000 today.
