Reacting to raids of California medical marijuana cooperatives by the U.S. Drug Enforcement Administration, several California cities are asking local police to stop cooperating with federal agents.  According to a Los Angeles Times report, the City Council of Sebastopol became the latest to approve a resolution supporting California's medical marijuana law and asking that the municipal police force avoid working with the DEA.  Sebastopol's vote Tuesday night is expected to be followed in a few weeks by similar action in neighboring Santa Rosa.  Earlier this year, city leaders in Berkeley and San Francisco approved anti-DEA resolutions.  In San Jose, Police Chief William Lansdowne in October pulled his officers from a DEA task force, citing a "clear conflict between federal and state law" and saying methamphetamine was a far greater problem than marijuana.  California Atty. Gen. Bill Lockyer has called the recent raids "punitive expeditions" that are an affront to the will of California's electorate.
