Actually silencers were not added tot he NFA because of some assassin paranoia. You just have to look at when the NFA was passed. During the great depression. When people had no food they turned to poaching. Silencers made that alot easier to do without getting caught. So they were banned.
I guess when the antis claim the 2A is anachronistic and invalid because it was written 240 years ago and "The founding fathers couldn't foresee"
We can reverse that on them. Silencers were banned almost 80 years ago. Things were different then. The government couldn't foresee all the food we would have nowadays and nobody would need to poach. Unban them
