A person may be qualified based on:
A courtroom gang expert is someone who has specialized knowledge, training, or experience that helps the court understand gang-related issues beyond what an average person would know. Under Evidence Code § 720 (in California and similar rules in other states), an expert can testify if their expertise will help clarify key facts or concepts in a case.
There are two main types of courtroom gang experts:
These individuals typically include police officers, probation officers, or investigators who:
However, their opinions can be biased, overgeneralized, or based on flawed or outdated information.
These are credible messengers with deep, firsthand knowledge of gang life, often including:
They may not have badges, but their understanding is often more nuanced and accurate, especially regarding how gang labels are misapplied, how youth are recruited, and how people change.
Our gang experts bring unmatched credibility, insight, and transformation. They have lived the gang life, survived decades in prison—many facing life sentences—and emerged with a renewed purpose: to help others break free from the same cycle.
What sets them apart is not just their lived experience, but the change they’ve made. These experts now work actively in communities and institutions to heal harm, mentor youth, and support justice system reform.
Here’s how they can assist:
No, not everyone who commits a crime is a gang member. In fact, many individuals who end up involved in the justice system have no gang affiliation at all. While gangs can be involved in criminal activity, not all crime is gang-related, and not all individuals charged with crimes are part of a gang. Mislabeling someone as a gang member can lead to unjust sentencing enhancements, stigma, and a misunderstanding of their actual circumstances. Each case deserves a fair, individualized assessment—one that looks at facts, not assumptions or stereotypes.
No, not all crimes are gang crimes. People do a lot of different things that do not benefit any gang. People do things to benefit themselves and have other very personal situations that have nothing to do with thier gang. There are many different examples of these crimes: personal issue with another person, domestic violence, stealing to support a drug habit or to survive to name a few.
It really depends on the gang experts experience, training, and education. You will need to talk to each expert to settle on a fair compensation. Generally speaking anywhere from $250-$1000 an hour, depends on the experts experience.
No, not everyone that commits a crime is a gang member.
Absolutely. Many of us are living proof. We were once deeply involved in gangs and served long prison sentences—but we changed. We got educated, healed, and dedicated our lives to giving back. Today, we work in social services, lead intervention programs, and serve as credible messengers in our communities. We show others that there is a different and better life beyond the lies we were sold and believed as youth. Change is possible—because we’ve lived it.
• We will need a Retainer Agreement that specifies how many hours we will be compensated for.
• We typically start out with 15-20 hours but could be 50 hours to start out. Every case is unique, so it just depends.
• if it’s only to testify a minimum of 5 hours for the day. Reviewing Documentation will be more hours.
• We will need to review relevant materials: psych evals, law enforcements gang expert testimony, info on client's youthfulness, upbringing/prior trauma, and anything else relevant to assist us in forming our opinion.
• We will need the referral questions of what your seeking our expertise on.
• We will need all the preliminary reports, police reports, discovery, police gang expert testimony, c-file, any psychological evaluations, and anything that will help us view the entire case and client as a whole person approach to best form our opinion.
• We will want to visit the client to solidify and better form our opinion. Remember a client might talk more freely with us then you,

PC 186.22b: the defendant committed, or attempted, a crime for the benefit of, at the direction of, or in association with a criminal street gang, and when the defendant committed the crime, he/she intended to assist, further, or promote criminal gang-related conduct.
Challenging false narratives about gang members and the motives for the crimes they commit. Examples of false narrative are-
1. Every crime a gang member commits is for the benefit and promotion of the gang.
2. All gang members present must actively participate in or assist in criminal activity or suffer punishment by gang members.
We effectively argue that there are many reasons that gang members commit crimes, "for the benefit of, at the direction of, or in association with a criminal street gang, and when the defendant committed the crime, he/she intended to assist, further, or promote criminal gang-related conduct" is not always the case. In fact, for most crimes that gang members commit that is rarely applicable. We aim to bring accurate information regarding gangs, gang culture and norms to promote equitable solutions in the courtroom.
