My research and experience over the past 50 years as a criminologist has involved me in almost every facet of the American crime problem. My research into all aspects of crime and delinquency, my therapeutic treatment of both criminals and juvenile delinquents in prisons and psychiatric hospitals, the writing of numerous books-including two widely adopted textbooks, my work in the field of crime prevention, and my role as a professor at several major universities has provided me with a wide array of knowledge that qualifies me for the role of legal consultant and expert witness in the criminal justice system. In the context of this background and experience, I have participated In the criminal justice system through aiding lawyers in the preparation of testimony, given depositions, and testified in court as an expert
witness in over 170+ judicial cases. Around 160 were gang cases.

I have been approved as an Expert-Witness in over 160 cases on issues of violent gangs, homicide, domestic violence, and business security in the Superior Courts of: Los Angeles County; San Diego County; San Francisco County; Riverside County; Ventura County; Sacramento County; San Jose County; Monterey County; San Joaquin County-Stockton; Allegheny County-Pittsburgh, Pa.; Orange County; Pima County- Tucson, Az; New York County; the United States District Court-Central District of California; and the State of Florida Law Offices of The Capital Regional Counsel.
Based on my background and experience in the Courts, The Committee of Judges for the Los Angeles County Superior Courts has placed me on "The Panel Of Experts" qualified to be appointed as an expert-witness in "Gangs/Criminology."

Following are some of the cases I have participated in as a legal-consultant and expert-witness: A violent gang murder trial in New York County Court. Based on my book THE VIOLENT GANG I testified on the structure and behavior of violent gangs; Consulted In preparation of testimony related to a Hells Angels Gang murder; Testified on the nature of gang behavior in a trial involving the first degree murder of a gang member by another violent gang member in Hollywood; Consulted on a case related to the value of security guards in a homicide incident in a community center; Participated in a case related to the responsibility and liability of a Home Savings and Loan bank in the robbery of a client outside the bank; Participated in a case involving the legal responsibility of a shopping center corporation related to a gang youth shot in front of an arcade in the mall by another gang member; Consulted and testified in a case related to an insurance companies legal responsibility for a client's relative involved in an accident that killed a woman. In particular, I have participated in over 80 cases involving gang homicides and violence. A major aspect of this expert-witness work is to determine who is a gang member in the context of Californiaís ìgang enhancement lawî 186.22. In addition I have participated as an E-W in the Penalty Phase of 6 Death Penalty Cases.

(a) Notable in my overall work as an expert witness was my testimony in a landmark case, known as the "Denney Case." Reginald Denny was one of eight victims in a specific violent mob situation that occurred in the April 1992 Los Angeles Riots that followed the court decision in the police-Rodney King case . I testified as an expert witness for the Los Angeles County District Attorney's Office on various sociological theories of collective behavior as they relate to the role and responsibility of individual criminal acts in the context of mob riot behavior, in a rebuttal to some assertions made by a defense witness in the case. About my participation in this case, one of the Los Angeles County District Attorneys wrote me, in part: "Your scholarly and articulate commentary from the witness stand helped to communicate to the jury that people must be held accountable for their violent behavior in the context of any kind of mob action. Your testimony was significant in the trial, and was very helpful to the prosecution in obtaining the convictions we did and gaining some measure of justice from these tragic events. The case resulted in a published decision by the Court of Appeal, People v.Williams (1996) 46 Cal.App 4th 1767. I look forward to using your services as an expert witness in this area if the subject arises in another case."

(b) In December 1998 I was invited to present a lecture to the Los Angeles County Bar Association on my work as a gang-expert witness. My presentation was well received and I received the following letter from the Director of the Program. ìIn my position as Director of the Los Angeles County Bar Association Indigent Criminal Defense, Appointments (ICDA) Program, I am pleased to sincerely thank you for your excellent presentation of your paper, ìThe Role of a Gang Expert-Witness in the Criminal Justice Systemî to our group of some 200 lawyers at our 1998 Winter Seminar. Your lecture was not only very interesting, it provided the attorneys present with some valuable insights into the complex legal issues of gang behavior that attorneys around the country increasingly have to deal with in gang court cases. As you cogently presented in your lecture, there are many myths and biases about gang members that can significantly affect the outcome of a jury's decision to either convict or acquit an indigent defendant. Many of the ICDA attorneys who attended your lecture have expressed to me their appreciation of your pedagogic insight into the behavior of gangs, and how this knowledge is useful in the rendering of just decisions in the criminal justice system. I am sure that many of the attorneys who attended the lecture, based on your extensive work as an expert-witness, have already used the legal and sociological arguments that you effectively articulated in their courtroom practice. We are most grateful for your articulate and pragmatic contribution to the work of our ICDA attorneys, and look forward to the possibility of a return lecture engagement sometime in the future.î Sincerely, Gustavo Diaz, Director. On February 4, 2001 I presented a lecture on ìThe Role of The Expert-Witness in Gang Casesî for the California Association of Public Defenders in Anaheim.

(c) In 2000 I testified in several gang homicide cases regarding the participation of several defendants in violent gang behavior. Notable among these cases [5/10/00] was a youth charged with First-Degree Murder who, in my opinion, had no gang involvement, and ìwas in the wrong place at the wrong time.î He had attended a wedding and was given a ride home by two youths who were previously unknown to him. They were violent gangsters who during the ride, spontaneously opened fire on a youth group, shot and killed one person, and wounded 3 others. In my opinion the youth charged with a 187 offense was more of a witness than a perpetrator. Based, in part, on my testimony he was acquitted on all charges. The attorney in the case wrote me as follows: ìI am extremely pleased to report that Gerardo, his mother, his aunt, and I (as well as a packed courtroom) listened to the clerk read 16 verdicts of "not guilty." What a relief! The defendant needed Kleenex as he had tears running down his face. He periodically looked at the jury and mouthed, "thank you." Mrs. A and her sister were also in tears in the audience. The two shooters were convicted of the most serious crimes across the board... Your name did come up in my short discussions with some of the jurors in the hallway. There were two jurors - one-lady in the back row and one man in the front row --who particularly liked you. They both said they were going to go out and buy your "Gangster" book. They agreed with my closing argument that the primary message that you brought to this trial was that one had to look at the overall picture, not just the negative factors, in deciding whether a person was a gangster. They felt that Detective A [the prosecutorís expert-witness] had overreached in labeling Gerardo a gang member and your analysis was more thoughtful. The front row juror-encouraged me to seek the removal of Gerardo's name from [the California] law enforcement's gang-database. I told him I would indeed seek that relief... I want to thank you for your hard work and intelligent courtroom presentation. Your counsel was something I valued and you certainly assisted me in better representing an innocent young man.î

From1951-1953 I performed all facets of work as Youth Division Supervisor at the Essex County New Jersey Juvenile House of Detention in treating juvenile delinquents being held in custody, awaiting court disposition ; Also during this period, I directed group psychotherapy and psychodrama groups with criminal/addicts at New York Cityís Rikers Island Prison, and the Riverside Hospital for adolescent drug
addicts; From1965-1982 I was a Consultant and Trainer in group psychotherapy and psychodrama methods to the psychotherapy staff at several California State Hospitals located at Camarillo, Metropolitan State Hospital, and Atascadero State Hospital; From1983-1994 I directed group psychotherapy and Psychodrama sessions with adolescent and adult patients at VAN NUYS PSYCHIATRIC HOSPITAL, COLDWATER CANYON PSYCHIATRIC HOSPITAL; and the C.P.C. WESTWOOD PSYCHIATRIC HOSPITAL where I was Director of Psychodrama and Group Therapy Services from1985 to1990.

Since 1985. I have directed over 30 weeklong workshops on psychodrama and group psychotherapy for mental health professionals at various correctional institutions, prisons, and training institutes in the U.S., Europe and Japan. This type of training was directed in Therapeutic Communities In Rome, Turin, Berlin and Athens. In 1994, by invitation, I was a consultant to the Japan Ministry of Justice and gave lectures in Tokyo on group methods for their Criminal Justice System. In l998, as previously indicated, I was invited by the Italian Government to utilize psychodrama and group therapy methods in the training of mental health professionals working with HIV/AIDS patients in three weeklong workshops at the CTS therapeutic community in Turin, Italy.

Since 1990, I have been a consultant and directed group therapy and psychodrama sessions for Amity Inc. with a variety of prisoners incarcerated in the California Department of Corrections Donovan Prison in San Diego and Lancaster Prison; and the Texas Department of Corrections prison in Beaumont, Texas. These projects involve special research and a psychotherapeutic effort at resocializing several hundred inmates housed in these prisons. The projects involves both ex-criminal and professional therapeutic agents in a "therapeutic community" modality for rehabilitating offenders in these prison programs.
