Mr Alanis's death, and the violent clashes that ensued at those cannabis farms, are the latest examples of the kind of chaos that has swept across southern California since the beginning of June, when immigration raids began to intensify in the region.

George Retes told reporters he was manhandled by federal agents who broke his car window, damaged his vehicle and sprayed him with tear gas.
