Demonstrators want the mayor and city council to take down the fence at the detention center.

City leaders say the fencing was installed after a demonstration July 1 to keep people off the railroad tracks in front of the NWDC. Protesters have consistently stood on the tracks and blocked gates. The fence runs the length of the railroad tracks and is parallel to a fence that already encloses the NWDC. Tacoma's city manager said the fence was erected after consulting with BNSF, which owns the land along the tracks.
