investigationsGlobal Security Group’s (GSG) investigators are all highly experienced veterans drawn from federal law enforcement agencies and the New York City Police Department and have extensive experience in conducting all types of criminal and civil investigations. Global personnel are also uniquely well-qualified to conduct undercover operations. Our operatives have extensive experience in that regard and have acted in that capacity in some of the most significant criminal cases in US history.

Global’s case preparation techniques, report writing and evidence handling procedures are based upon those used by the most highly regarded federal agencies. All of Global’s investigative personnel are experienced trial witnesses and have been qualified as experts in federal and state court on many occasions. The extensive experience they have had as law enforcement case agents and officers enables them to prepare and structure all investigative materials in the most effective manner for litigation purposes.

The investigators at Global are experts in the use of highly sophisticated technical investigative techniques including digital video surveillance, crime scene and computer forensic analysis. They all have experience in conducting international investigations as well as cases involving intense media scrutiny.

GSG senior management includes a retired Captain of one of New York City’s busiest detective divisions and a former senior special agent with the U.S. Department of Justice / Drug Enforcement Administration. Our practice therefore, combines the best elements of the investigative methods of both federal law enforcement and the US Department of Justice and the New York City Police Department Detective Division.
