On the 11th of July, protesters against the Keystone XL tar sands pipeline showed up outside a hotel at 16th and M streets where Obama was scheduled to speak. The Sierra Club was heavily represented, the objective was to remind Obama to reject the pipeline.
Nearly an hour before Obama arrived, cops shut down both M street and 16th st, causing serious traffic backups throughout downtown. The Sierra Club did not resist orders to cross to the east side of 16th st. A lockdown would have probably delayed or even cancelled the speech, but might have been too strong for the “reminder” the bird-dogging campaign at all Obama’s speaking stops is intended as.
Obama is supposed to decide this month (7-2013) whether or not to permit the Keystone XL tar sands pipeline to cross the border with Canada.
