Numbers don't lie but they also don't always answer the question. I think either suggestion would work. 1. Remove all guns from citizens and government, or 2. Give guns to all citizens and government. The 1st one wouldn't work because ther is no real way to remove every gun for citizens and the government wouldn't disarm itself. The 2nd could work. I bet the drive by shootings would stop when the car got filled with holes from both sides of the street as it tried to get away. :) Just a crazy thought.
John Stossel interviewed prison inmates who said they would never consider robbing a person if they thought there might be a chance of them being armed.
Making guns harder to get would only increase gun crimes. Less guns equals less self defence from criminals.
tougher gun laws only make it harder for good people to get guns. Jamal McThuggenstein is still going to be able to get guns illegally no matter how hard it is to get legal ones.
