Criminal investigator

Lawful violence expert, PI trainer & principal

Greg Walsh offers 30 years of public safety and criminal investigation experience spanning 5,000 violent emergency incident responses as a law enforcement officer, forensic and defense investigator, rescue paramedic, trauma team member, and tactical EMS/law enforcement commander.

His lethal force experience includes over 750 penetrating weapon assault cases and over 500 federal and state criminal cases as lead defense investigator.

Greg is uniquely qualified for violence cases, having served on murder cases as a rescuer, state investigator, defense investigator, witness, and juror.  He received and developed specialized training in lawful violence, applying experience from hundreds of lethal force cases. 

The dismissal or acquittal rate for his criminal defense clients asserting lawful use of force exceeds 80%.

Greg Walsh is the author of Defensive Violence: Ethics, Tactics, and the Law.

Greg is an approved CJA panel expert by the US District Court for Western Washington, and served as lead defense investigator on cases spanning Treasury fraud, organized crime, outlaw motorcycle gangs, racketeering, international drug smuggling, arson, weapons and explosives violations, and witness intimidation. 

His government and police misconduct investigations  have exposed malfeasance, evidence destruction, collusion, perjury, prosecutorial misconduct, witness tampering, fraud, and civil rights violations.

As the only WA armed private investigator dual-licensed as a paramedic, Greg is regularly in demand for violence prevention, personal protection, and counter-stalking.  

Greg remains active as a helicopter rescue and critical care paramedic and EMS instructor, and has been qualified as an expert medical witness on the kinematics of violence trauma. He served as deputy medical examiner with the NM Office of the Medical Examiner, the premier US forensic death investigation system.

Greg is available for public and private appointment on felony and violent misdemeanor cases, civil cases involving human rights violations and police and government misconduct, and violence prevention, order enforcement, and counter-stalking cases. 

Greg occasionally serves pro bono on cases involving the use of force by private citizens wrongfully accused, Heller issues, and the natural right of everyone everywhere to responsibly and effectively prepare for, and resort to, defensive violence.
