Hey guy's, you forgot something important!
H.R.3999 - A proposed "bill to amend title 18, United States Code, to prohibit the manufacture, possession, or transfer of any part or combination of parts [e.g. "bump stocks"] that is designed and functions to increase the rate of fire of a semiautomatic rifle."
So, what is the 'standard' rate of fire for a semi-automatic rifle? How can an "increase" in the rate of fire be established if you don't know the standard rate of fire?
H.R.3999 is a good example of the kind of poorly crafted law that cause painful grimaces from those who are charged with enforcing it, not to mention the millions of law-abiding citizens who are left wondering where they stand in compliance.
At best, poorly crafted, vague or ambiguous laws leave the door open for abuse, as pointed out in the following video:
I guess this is a good example of why we need a "Committee on the Judiciary" ...
