A hearing officer has ordered the dismissal of a Durham cop found guilty of misconduct after the violent arrest of a mentally ill man.

Constable Craig Wiles “failed to show even a scintilla of empathy” when he pursued and arrested the man, kicking in the door of his Ajax home and screaming at man’s mother, according to retired York Region deputy chief Terence Kelly in his ruling on sentence, released last week.

“The extent of this misconduct was to such a degree that the suitability of Const. Wiles remaining an officer in this police service has been nullified,” the hearing officer wrote. “His behaviour on that fateful day was absolutely inexcusable.” Kelly ruled that Const. Wiles, an eight-year veteran of the Durham police, be required to resign or summarily dismissed.

The convictions, for discreditable conduct, unnecessary exercise of authority and excessive force, are the latest in Const. Wiles’s tumultuous tenure with Durham police. He’s been found guilty three times of using excessive force. One of those incidents, an assault on a female prisoner, also led to a criminal conviction for assault.

The latest incident, which sprang from a minor accident in Ajax on Harwood Ave. in September 2011, led prosecutor Ian Johnstone to call for the officer’s dismissal, a sanction the hearing officer ruled is warranted.

“I would be derelict in my duty and unfair to all other members of this police service if I were to inflict upon them someone with all these problems (being) allowed to continue as a serving officer,” Kelly wrote.

The tribunal heard evidence that Const. Wiles and his partner, Const. Ryan Kapeluk, were on duty on the afternoon of Sept. 21, 2011, when they encountered traffic stopped on Harwood Avenue and saw a pedestrian who appeared to have been involved in an accident with a vehicle.

Upon seeing police, the pedestrian, a 29-year-old man, fled to a nearby home with Const. Wiles in pursuit, the tribunal heard. The officer followed the man to the house and kicked the door down, burst inside and screamed at those inside to “get the f--- down.”

As he was placing the man in handcuffs, Const. Wiles was informed by the suspect’s mother that he is schizophrenic, according to the ruling. The officer placed him under arrest and marched him to a waiting cruiser, on the way “grounding” the man twice as he screamed and struggled. During one of the groundings, Const. Kapeluk, who had come to assist, sustained an injury to his arm, the tribunal heard.

Kelly found that Const. Wiles pursued his course of action without learning the true nature of the incident, and that he had used excessive force in subduing the suspect.

“Const. Wiles simply allowed his emotions to take control and he became enmeshed in his own pursuit of these matters to such an extent that he was blinded to his clear obligations of his oath of office,” he wrote.

“He failed to show even a scintilla of empathy toward this young man, or his mother.”

The tribunal heard that Const. Wiles has been undergoing treatment for depression and anxiety. An evaluation by police brass found the officer had a history of public complaints and would require constant supervision to avoid more incidents, the tribunal heard.
