The document doesn't dispute the attorney's rationale or foreshadow it, but it does provide some guidelines for those in the business who want to avoid the long arm of the Obama administration.
"The memo looks like what I would have suspected federal guidelines were all along before the crackdown," Dale Gieringer, state coordinator of California NORML, told the Weekly today. "It's a useful indicator."
But Gieringer warned medical growers that having 199 kilos or 999 plants won't necessarily protect them from prosecution. He said the DEA marches to its own drummer on that stuff: "DEA raids don't necessarily conform with this," he said."
