My thoughts on the Supreme Court's decision to allow guns individually

Recently, the United States Supreme Court ruled 5-4 that the Second Amendment of the United States allows individuals to keep firearms. I've generally been in favor of gun control, but lately, I've been getting increasingly cynical, and I'm wondering whether it's such a good idea after all. Here's why.

• No matter how much, and how strict of gun control we have, someone who is determined to kill someone will still be able to get their hands on a gun.
• If people were properly trained about how to use guns defensively, they would be able to kill someone who went on a shooting spree.
• People would be less likely to assault someone because of the consequences.

However, even I can't get myself to accept these facts. The thought of everyone being armed scares me. There's just too many irrational people in the world. It seems like there's no solution to this problem. And when you throw in that we need an armed population to keep our government in check...

There's just no right answer.
