I am not trying to convince you of anything

I have no idea what they are struggling over. I don't really care either, as long as they keep it amongst themselves, and keep in behind closed doors. Which of course they do not.
Just don't make this a pot legalization issue. There is no reason to link these killings with legalizing or not legalizing pot.
We assume it is drug/gang related. We don't know. When I hear "drug related" though, I think coke, XTC or other hard drugs. Not pot. I have never seen shootings over pot (in pot country Holland that is).
