So, here again we hit the question, how can these things happen since you already have extremely restrictive gun laws? Your solution is, more gun laws?
You act as if guns and/or alcohol are recent innovations and that only now citizens are getting access to guns. The exact opposite is true and societies now have less guns on a per capita basis than in the past. Yet somehow, the population in years past wasn't decimating itself in drunken shooting rampages. So how come all of a sudden this is the solution to what is a very small problem?
Some of that gang-related stuff. Again, guns are hardly a new innovation -- perhaps it's time to use some of that energy being used to restrict peoples' freedom by restricting a tool and start to work on what is causing the behavior and attitude instead. What is so laugh-in-your face funny (again, but for the serious consequences) is the notion by gun ban advocates that somehow guns have just appeared on the scene and are now causing this whole new problem. The reality is that gun access for all citizens was actually greater in those days you are reminiscing about. Kids used to take guns to school for a variety of reasons: gun club, show and tell, and to hunt on the way home after school. There weren't wild rampages then, so guns aren't the problem, why do you think banning them now would be the solution?
The whole idea that by banning an inanimate object along with the accompanying unintended consequences and side effects will somehow solve the problems you describe above would be laughable if it weren't so darn serious for the peasants (what disarmed citizens become) who are subjected to such regulations. The gun control part is just part of the total package -- just look to England. After disarming the citizens, the next step was the idea that "a few farthings worth of x is not worth someone losing their life over" and now you have the case where defending oneself in one's own home leads to jail time for the person doing so. People still die in fights, so the statists start looking for the next problem -- now there are people in England seriously discussing regulating and banning knives. [You just can't make this stuff up].
All deaths are tragic, society seems to be onto this notion that somehow the world can be made completely safe through the application of various laws and restrictions. The problem is that those laws and restrictions have other various serious consequences and side effects. Where I grew up, and where I live now, law enforcement is a minimum of 30 minutes (most likely
45 minutes) away -- you are proposing disarming people like myself and putting us at the mercy of those who are already breaking the law. Mighty compassionate of you.
