Two years ago, Ger Chong Ze Chang was driving to his home outside Dorris, California, near the Oregon border, when he was stopped by a Siskiyou County sheriff’s deputy. Chang recalls that the deputy walked up to his car, with his gun drawn and pointing downward, and ordered him to get out of the car. After he searched the car and confiscated a knife, he let Chang go without a ticket. But a year later, Chang said, it happened again: He was pulled over in the same place on his way home from the laundromat, searched, and ordered to dump his just-cleaned clothes out on the ground. In both cases, he says, he was never even told why he was being stopped.
