Expert John "Jack" Ryan first appeared on the witness stand Monday. He provides training for police officers nationwide, does audits of law enforcement agencies, and has helped write policy in over 20 states. He also serves as an expert witness in civil and criminal litigation and was a police officer for over 20 years. On Tuesday morning, the defense for Officer Burbank, Wayne Fricke, pressed Ryan on whether the use of force in this case was reasonable or not. Ryan said on Monday that the officers' collective use of force against Ellis was "excessive." Fricke pointed to a Tacoma Police Department manual that gave officers permission to go outside the typical "tools and tactics" of their training when in an unpredictable situation. Ryan acknowledged that was true, but emphasized that force still had to be reasonable and necessary. Ryan later said it was a "totally inappropriate response" for officers to sit on Manuel Ellis' back while he was handcuffed, face down.
