"...and the second is like it; you shall love your neighbor as yourself."
Except in Canada, where we read this command as "You shall leave your neighbor by himself."
Most of you have probably heard by now of the (surely) demon-possessed fellow who stabbed and decapitated a fellow passenger on a bus in Manitoba. How many people were on that bus at the time? It surely takes at least awhile to complete the deed of removng someone's head, why did nobody intervene? There were lots of things at hand that could have been thrown at him, to distract him long enough for somebody to tackle him and disarm him.
He could have been stopped cold, before he did the deed, if it were legal to carry concealed firearms in this country. In fact, you can be sure this would not have happened at all if that were the case...
I strongly suspect that there will now be a push to outlaw knives in Canada. Just watch.
