Sorry cloud, I'm not seeing your point.
A .50 cal magnum handgun has more stopping power than most rifles. Why do people use rifles in hunting? They are more accurate. Its hard to use a hand gun and a scope. Why do the amish use hand guns? I dunno, I guess they need schooled.
Why are people afraid of what guns can do? No gun is any more dangerous than other. Its the intent of the person that has it, not the weapon itself. Didn't 911 prove that relatively harmless devices (planes and box cutters) can be extremely deadly! What about Oklahoma City? Fertilizer!
Is it OK to have acetone peroxide? Sure! Fun for the whole family....if you follow the rules and regulations setup for its use and you are responsible for it. If you have a rock on your property, and you want to blow it up, and its legal, go for it. Blowing up a bus? If its yours, and its legal and its not hurting anyone, sure! Its yours. Responsibility is the key. Morons like those in London shouldn't have had it. They hurt people, and broke the law. They should be found and eliminated.
Weapons are what you make them. They aren't deadly on their own. Isn't that what our second amendment says? We are allowed to carry and own weapons? But the key is -> you can't be stupid and irresponsible.
Oh - and by the way. If you make fun of me or my name again, you WILL invoke the master. Be careful what you say...
