I agree and these are good points. I have heard the pro-gun side, I know people with arsenals, and I have heard the anti-gun side too, even people that if you think I am anti-gun, these people would give me a run for my money!
It's what I was meaning earlier in the gun topic about that downward spiral. More guns and gun crimes feeds the narrative for the government to do gun control, people hate the government so they in reaction get more guns which leads to more gun violence and opportunity for gun violence, which then leads us back to the government wanting more gun control. Keeps going on and on, yet it is not a cycle, it is a spiral. Unless even some modest attempts are made, it has to crash at one point into either total full blown Wild West anarchy or into government tyranny, which is what no one wants.
It's an irony really. In order to maintain the gun for the law abiding, they have to get on board with some sort of gun control. If they don't, then either nothing gets done and the gun violence keeps growing, or elsewise the people that actually want the government to totally disarm everyone have an excuse to do such. It's kind of like Obamacare, because no one did anything about healthcare before, now we got something that pretty much no one likes when they could have easily just done some simple little reforms.
As for the Constitution, scrapping it is always a possibility, but one doesn't have to go to that extreme. There's all ready a precedent in the bill of rights that one can essentially repeal or nullify amendments which is itself totally constitutional. The Constitution is also only the law of the government, it's not the law of the people. So one doesn't even have to even go to that extreme either. The more meaningful solutions to gun control don't even necessarily have to involve the government at all, but that is what makes them harder, because it takes the will of the people.
To the converse of that the solutions that do involve the government, such as confiscating guns from criminals, well they don't have a right bear arms to begin with being criminals anyways. The gangsters are even like unto rebel armies, so it is almost imperative that the government disarms the gangsters whom are openly killing American citizens and government employees like the police.
