Driving away from a very entertaining and impressive MLKBallet MOVE! performance at the Tacoma School of the Arts 20 minutes ago I ran into a police blockade at 11th and Market and another on the other side at Ninth and Market.  Did the audience at the Northwest Sinfonietta riot tonight at the Rialto?  Anyone know what's going down tonight?  The sirens are still shrieking. â€" Suzy Stump
