If you’re not familiar the gun rights thing is insane. You have to understand the founding fathers feared a standing army. Just look a what they’d seen in Europe. Hence the well regulated militia and the right to keep and bear arms. It’s the last word arms. Arms of the 17th century are a far different thing from arms in the 21st century.
There have not been any updates just mistaken rulings from the courts. This runs counter to the regulations the administrative branch has tried to stop the inanity. But now we have 19: children and two adults dead. To keep doing the same thing is insanity.
