Virginia Tech Had Gun Control

Virginia Tech already had gun control laws in place preventing anyone from defending himself and stopping the crazy person.

Why isn't it obvious that gun control only leaves the majority of people defenseless but still allows the killer a way to find a weapon? And gun control happens when people want to put more trust in their government than in themselves. I found this writing on the topic.
