In 2003 Seattle voters passed an ordinance that was supposed to make simple marijuana-possession cases the “lowest priority” for law enforcement. Apparently Seattle Police lost that memo last year.The P-I’s Chris Grygiel reports:Seattle police referred almost three times as many possession of marijuana cases to prosecutors in 2010 compared to 2009, but City Attorney Pete Holmes says his office only filed one – and that was a mistake.The information comes from Holmes’ annual report, which he presented to the Seattle City Council last night. Packed into that report, among other things, is this little nugget.That’s quite a jump.Seattle Weekly submitted its own public-records request to SPD, which should help us further extrapolate those numbers. We’ll post the info as soon as we get it.In the meantime, if you’ve received a ticket from SPD for pot possession (and by the numbers here, there are quite a lot of you), go ahead and fire up a victory blunt, because there’s almost zero chance you’ll actually get charged.
