Gang allegations do two things: they add years, and they let the prosecution put evidence in front of a jury that would otherwise never see the light of day. Tattoos. Photographs. Old police contacts. The “expert” who takes the stand and tells twelve people what your client's life means. Mr. Nguyen spent eight years in the Alternate Public Defender's office, where gang cases and multi-defendant gang cases were routine. He has litigated gang enhancements, challenged gang expert testimony, and cross-examined the officers who build these cases for a living. Recent changes in California law have significantly narrowed what the prosecution must prove to sustain a gang enhancement. Those changes only help if your lawyer knows how to use them.
