Contractor workers for the U.S. Army Corps of Engineers begin painting over the gigantic letters, "MTA," along the concrete bank of the Los Angeles River October 8, 2009. "MTA" stands for "Metro Transit Assassins." The letters are three stories high and the length of five football fields. Authorities contend the letters were painted on the riverbank by up to 40 taggers, 14 of whom were arrested in January and are still awaiting trial. (AP Photo/Damian Dovarganes)
