The Supreme Court declined to take up a challenge to Connecticut’s semi-auto ban. That was not a surprise given they are one justice short at the moment.
This is not the end of the issue. Some people think that Heller and McDonald settled the gun control debate when in fact they were more of a starting point. We need to look at things from a long term perspective. It took nearly 40 years for NRA and others to set up a legal framework which got us Heller. It is entirely possible that it will take a couple of decades worth of court decisions and legal scholarship before the next right case makes it to them.
Jacob, assuming we are close in age, we probably wont see it. LOL.
