Dear U.S. Attorney John Walsh:

As fellow law-enforcement colleagues vitally interested in the health and well-being of children, we must respectfully register our fundamental objection to your recent issuance of 23 letters threatening state-legal Colorado Medical Marijuana Centers and their landlords with civil, criminal and forfeiture sanctions. That you would justify this action on the basis of the locations in question being too close to schools for your liking (compliance with state and local law notwithstanding) is ironic and highlights the failure of the very federal marijuana prohibition policy that underlies the threats in your letter, as we'll explain.

Certainly, you must be aware that the voters of Colorado and the Colorado legislature – like the voters and lawmakers of 16 other states – have made it abundantly clear that marijuana is medicine for many people and for many ailments, and that its use and provision to patients should be allowed under the law.

Almost two years ago, in a bipartisan fashion, the Colorado Senate and House of Representatives enacted a strict dual licensing system for Medical Marijuana Centers that requires a license by the local and state government. All the businesses you have targeted are operating with approval from their local governments and the state of Colorado.
