Turning around seventy years of failed drug policy in America is like making an aircraft carrier do a U-Turn. It takes a while, even after the steering wheel is moved. So even though the Department of Justice has stated that it could care less about medical marijuana, the Treasury Department has been telling banks they could be prosecuted for serving dispensaries. Bloomberg is reporting on a letter sent from Congress to Treasury, wherein fifteen members of Congress ask Treasury to stop telling banks that. Turns out, Bank of America and San Francisco-centered Wells Fargo have been routinely denying banking services to dispensaries, ostensibly to protect themselves against federal prosecution.
