In South Gate, police had already been warned: Just expect that you might be filmed with cellphones and other cameras as you do your job.

After high-profile uses of force caught on video in places like South Carolina, New York and L.A.ís skid row, officers in the Southeast L.A. suburb had been told to take filming in stride. If you're not doing anything wrong, police brass reasoned, what do you have to worry about?

So on Sunday, when a lawman was caught on video snatching a womanís cellphone in South Gate as she recorded and smashing it on the floor, it was with relief that South Gate police said the officer wasnít one of their own but a deputy U.S. marshal.
