They haven't resolved shit. Fact is it's not about "cutting off the head and it dies". It's more about "kill one, two will replace them". There is money and opportunity in the drug trade and anyone who wants that money will take that risk.

Then again, we could probably follow suit, by lining people up in the street and executing them like it's wartime. That will surely solve the issue...

...or criminals will just get smarter at hiding their activities.

Symbolic politics with bloodshed, really.
