Canadian authorities, acting at the behest of the DEA through the Mutual Legal Assistance Treaty (MLAT), have arrested pro-cannabis activist Marc Emery on charges of "conspiracy to produce marijuana and distribute marijuana seeds, and money laundering".
Canadians are expressing outrage at the subjugation of their sovereignty to the will of US anti-pot crusaders.

Emery has funded his pro-legalization activities through the proceeds of his internet cannabis seed sales website. Possession of seeds is legal in Canada.
The DEA is sporting wood over this.
Canada is generally seen as having a more rational and humane attitude towards cannabis, and has recently approached the idea of legalization for personal use.
