Uhhh why would they do that when they can just buy them for super cheap at industrial scale from the US?
And yes the solution to things like organized crime is always just a continuous chipping away and adding friction where you can.
Not giving them massive amounts of cheap, high quality firearms seems like a meaningful goal.
This is a popular idea amongst American liberals who rejoice at any possible means to eliminate/curb/add friction to lawful firearms ownership and manufacturing.
Where are they buying firearms in America at an "industrial scale?" An AR-15 receiver can be turned out in tens of minutes on a fast VMC - good luck stopping this.
I think the point was: it might be a bit more expensive for them, but it wouldn't stop them from getting guns. Guns are important to their business, they would manufacture them themselves if they could not buy them.
Would it cost them more? yes. would it be the "number 1 priority" because it's so impactful? no, obviously not.
