If their security guards are going to get violent, DC police should arrest them on the spot like any other violent criminals and actually charge them with crimes and hold them for trial.
Video of the following days altercations at Sheridan Circle captured Turkish security guards outside the ambassadors residence ignoring police commands and breaking through their lines. It shows them ripping posters, tackling and kicking people in the crowd, and fighting with police who struggled to maintain order. A 61-year-old man suffered a concussion and lost a tooth when he was kicked and beaten in the head, according to an account in the civil suit. A woman was attacked while pushing her child in a stroller.
Authorities detained two Turkish officers, putting at least one in handcuffs and seizing his weapon as authorities debated whether to make arrests and discussed the legal complexities of diplomatic immunity. The security officers were later freed and the gun returned as the men boarded the airplane home later that night. One memo says the Turkish ambassador had pleaded for the officers release from custody by looking past what had happened.
