The news makes sense to me -- after all, he probably has more experience with them than anyone else on DC's city council. As you might recall, Barry spent six months in federal prison after the FBI caught the DC mayor smoking crack cocaine in a sting operation in 1990.
For some reason, however, the Huffington Post calls Barry, now a city council member, an "unlikely" proponent of the decriminalization of marijuana:
The fight to decriminalize marijuana possession in Washington, D.C., just got an unlikely ally: former mayor and current city councilman Marion Barry (D-Ward 8).
Barry and fellow council member Tommy Wells (D-Ward 6) are drafting legislation that would reduce or eliminate criminal penalties for people caught with small amounts of marijuana.
“It’s time we enter the 21st century and stop criminalizing people... for what is not really a major crime," Wells told The Washington Post.
