Yes the stealing plants is a shit thing to do I agree. However, I will also agree it is very unlikely that someone is gonna shoot you over it in Canada. Maybe in the US but not Canada.
US gun related homicides 2005 - 10,100
Canadian gun related homicides 2005- 222
(of which most are located in urban centers) 56 in Toronto with Vancouver and Montreal totalling just as many, so there would only be 110 left for the other 20,000,000 in Canada
And if you take into consideration US has 5x larger population, it would still only be 1998.
And since the gun registry, shotgun and rifle related homicides are plummeting in Canada.
Canada averages 60 drug related homicides each year, this would also include people who were on drugs while the act was committed, as well as deals gone bad, so I'm going lowball a guess that this takes care of 50.
That would leave an average of 10 people getting murdered by firearm per year...i'd say its unlikely
Or just divide 110/20,000,000= 0.0000055
Yes, stealing marijuana is a sad thing to do, but in Canada it would rarely constitute murder. We tend to speak loudly...and carry a little stick.
