The reason why I am firmly opposed to any kind of gun control at this point is both that I think our laws are currently sufficient, and that most anti-gun legislation that has been proposed has been a back door gun ban. Charging a multi-dollar per round tax on ammunition, banning anything that can "penetrate a standard police bullet proof vest" (every rifle, basically), legislation requiring you keep your gun locked in a safe at your gun club (thus making it pointless for anything except use at said hunt club). It sucks when innocent people are hurt. It sucks when it is in schools, it sucks when it's in a traffic accident, it sucks when it's in the stock market. When guns are banned, it's still possible for someone who leans that direction to commit mass murder. The problem is that some people still feel like murder is an option. That someone can know that they can make a mark on history by blowing themselves up, or shooting up a school. Our laws protect the names of the victims, but our media promotes the criminals. We treat people who get treated for mental illness as criminals. We give lip service to stopping bullying, but it still happens every day, both on personal and institutional levels. Not only will banning guns not solve society's problems, I don't think it will even make a dent. If you want to make a difference toward preventing incidents like what happened today, say hi to someone who's marginalized. Listen to them when they talk. Help them if you can. Don't punish the law abiding people.
