I wonder if the Russian people had guns if Stalin would have been able to kill 60-80 million. Mao, Pot, Hitler all disarmed the people prior to killing so many millions of their own people. Gun control has not stopped terrorism in every country - home grown or foreign.  

Plato - only the dead have seen the end of war. 
Even our own government using biological warfare against native Canadians - 
All Governments enforce their will at the end of the barrel of a gun or what ever means they think necessary... All Governments left unchecked become despotic - all. 

And, God forbid that the food supply is short - then you will see just how civilized Canada really is. 3 Days of food in the stores - that's it. There will always be people committing heinous crimes - that is one of the primary statements of Darwin (if you believe that sort of thing) - "survival of the fittest." 

Humanity is depraved - period.
