All I can say is that I'm getting tired of the monotony of the whole thing. As Obama said, we're becoming numb to the whole thing, and that's not good.
I'll say this, the whole debate is placing way too much emphasis on guns. One side paints guns as the cause of all our problems, and the paints them as the solution to all of our problems. Yes, guns are used in various violent crime and the US has some of the highest gun death rates in the world. Yes, guns have also been used in various cases of self-defense and have in fact saved lives (though at the cost of the criminal's life(s) at times).
However, the anti-gun side seems to ignore the intent to do harm, as opposed to the means to do harm. The UK supposedly have very strict gun laws, but the knife-related crime rate is extremely high. I have heard that despite Australia banning guns, they suffered an extreme amount of gun-related crimes. These people need to understand that making something illegal will not deter everyone from doing it, and it a person is that determined to harm people, they will find a way to do it.
As for the pro-gun side, cases like this demonstrate that, despite all the talk of the second amendment, there are people out there whole just shouldn't have access to guns, weapons, or objects that could be used to harm others for any reason, EVER. After all, places like Japan have strict gun laws and violent crimes are supposedly low (you take that statement with a grain of salt), though it seems most people there are more likely to hurt themselves than another person. This has to do with culture and people's attitudes toward violence. Not to mention, I remember hearing the last few shootings occurred because the perpetrator was able to get a weapon despite not completing a background check.
As a martial artist, I believe the average citizen's right to protect themselves, from criminals, tyrannical governments, or whatever should not be violated. However, those same people have to be able to demonstrate responsibility and compassion when it comes to owning a deadly weapon. Thankfully many institutions exist to help educate people on responsible gun ownership and safety, but when you also look at places like Florida, whose "Stand your ground" law will give anyone the excuse to kill someone over bullocks, there's always going to be some asshole to take advantage.
So, what do I think people should do? Tighten up the laws we have on the books and place more emphasis on proper conflict resolution and using deadly weapons as last resorts to a violent situation.
