If that was the case, it would be equally inaccurate to say that the moniker "flamethrower" is insisted upon by flamethrower owners.

I'm not sure if just anyone can pick up a truckload of items which cost $600-1200 on average

Connecticut, New York, New Jersey, Colorado, and California are the ones where new laws passed, I believe. Similar laws were presented on a federal level, and in most states.

Two things: What would you offer as a remedy to the problem of gun suicides, and why is it your business to try and protect me from myself

I'm genuinely interested in hearing you define "semi-automatic assault-style rifles."

I assume the author meant accessible in the sense that laypeople could understand it easily
