But if we had more gun restrictions, then the perps wouldn't have access to these guns, right?

What "more restrictions" could there be besides the already existing NICS check, the Rapback check, the state criminal record check, the state mental health check, the state medical records check, the 14-20 day waiting period for handguns, the ban on all kinds of firearms/magazines that are totally legal in many jurisdictions that have lower crime rates than Hawaii? All that's left is a ban on all firearms, period (well, and continued bans on electronic weapons, etc.). And just because it didn't work in Washington D.C., and Chicago because the criminals could "go next door" and get guns there, it would
have to work in Hawaii because there is no "next door" to drive to and get an "illegal" gun, right? It would be so easy to create heaven on earth if the politicians would just do what they really want to do, ban all firearms from "civilian" ownership, instead of pretend they support and uphold the U.S. Constitution and the Hawaii State Constitution as they (lied and) swore to. But I seriously doubt they are going to do a 180 and start being honest at this point.
