3 Bumps and a crank in Chicopee, one bump somewhere in Essex county.
Gun owners have been proven time and again in studies to statistically be the most law abiding citizens out there. According to a Florida study owners are less likely to commit a crime than the police. While owners may have opted to destroy or sell their bump stocks, it can be safely stated that lawful gun owners completely complied with the law, if not the states unconstitutional threats.
Due to the original wording of the AWB bump stocks are only legal on pre-94 lowers- can't put a bump over a pinned stock, and if you pin a bump it becomes useless. This circles back to my original point of compliance- there were so few of these in the first place the state shouldn't be shocked by the low turn in numbers. Using "low compliance" rhetoric as justification for door kicking could only blow up in the states face. Don't buy into the media frenzy, these things could never have been out in mass numbers not only because of pre existing laws but because bumps were dumb range toys. Law abiding citizens who statistically are unlikely to commit a crime aren't ignoring the law, unless of course someone thinks that somehow this group of people have been previously pushed to a position where their willingness to abide by law- the foundation of law itself really, is no longer agreeable. In such a position, any ruling body should stop and think about how to amend such a broken bridge as any law passed targeting that population may too be ignored. If laws are wantonly disregarded, are they laws at all?
