You got it Randy, we need to prevent the wrong people from getting guns.
Now, why are people scared of "assault" rifles? Two reasons - the look of them, and not having enough education.
First, lets look at this gun here:

Now, this looks very scary, a full out military weapon right? I own this gun. It is a simple .22 rifle. I have two 25 round magazines with it. Perfectly legal to have, I use it to shoot gophers, rodents and targets. There is nothing wrong with this gun, it is the same as the old .22 that your parents and grand parents used.
Now compare these two:

2)

Both of these guns are .308. Both are legal to own, both are legal to hunt with. The thing is people are scared of the first one because it looks bad.
If you want a silly rule in our gun laws, that first picture of the .22, I can legally go out and buy a 100 round drum style magazine for it. These scary "assault" rifles, they are restricted (in Canada) and are limited to a 5 round magazine. Now, several states in the US have different magazine size limits, some are 10, some are 30. Does this mean that a criminal cant get a 30 round magazine in Canada for his restricted gun? He sure could. Its 100% illegal and he could face up to 10 years in jail if caught with it. CRIMINALS DONT CARE. So to say that assault weapons mean more killing is wrong, a person could get a 100 round magazine on a legal to use .22 and have just as deadly effect.
Now obviously the rules in the US are different then we have here, and I am not in favor of gun violence. I own and use guns responsibly, and I enjoy the sport of shooting. People need to be made aware of what guns are, and be properly educated on them, before we have these people making laws, when they just don't know.
It doesn't matter what a gun looks like, if used for the wrong reasons, it can be deadly. It doesn't matter if it can fit in your hand, or it takes 5 people to move it. Yes, there are military weapons, and those are used for war. Do we need to own heavy weapons like that? No, but should we be able to shoot them in the right, controlled places (like ranges)? Why not?
Granted, my examples don't all end in mass murder (well planes could be), but the point is the same - you cant ban one thing because of the actions of one person. Otherwise, all my examples are valid. Could a person use a car to kill multiple people? Sure could. He could drive through a crowded area and that would be devastating.
LeafsM - Unfortunately, with (some) people being as messed up as they are, be it by anger, uprising, parents, friends, religion, anti-religion, political views, sexual views, etc....people WILL find a way to harm others. If you think taking away all guns in the world will prevent some people from doing harm to others, you are wrong. If you were right, why, oh why, in the last 100 years hasn't our leaders came up with this idea? And why hasn't it been implemented. Why do we need our military's equipped like they are, why do we even need militarys? If there were no guns, there would be no violence right?
