I agree with you Johan, the line was drawn in 1791 with the words, "in
no way infringe".
The bill of rights and constitution are just pieces of paper that cannot
protect us. WE need to protect those rights, and those that passively
condoned the 1934 NFA committed a grave error.
It was like passively condoning your wife sleeping at her boyfriend's
house. Next she sleeps with him in your house [1968 GCA], and next she
wants you to move out [1994 AWB].
The moral is, "Don't tolerate the transgressions."
