“Make the penalties bad enough and people will turn them in.”
You might ask the Govs of NY, NJ, MA, CT, & WA about the noncompliance rate for mandatory registering of semiautos. Running about 85 - 90 percent IIRC.
Yeah, a lot of semiautos were turned in in Oz, but that’s because they were already registered. But there are still thousands in private hands.
And in New Zealand there is a media blackout after semiautos were made illegal to possess. If the ban were widely complied with, it would be shouted to the heavens.
Any new gun grabbing laws will have a long way to go to where the rubber meets the road.
“Police chief won’t identify gunman yet, says he doesn’t want to give shooter attention”... translation.. “gunman will not be identified because he doesn’t fit the profile of a Trump inspired white nationalist”
