Not quoting the whole article, but here are some choice bits:
Misconduct charges are expected against 45 Toronto police officers involved in the G20 summit two years ago, including five senior officers, one of them the commander who gave the notorious order to "kettle" protesters.
The report says some of the responsibility for detaining several hundred people for four hours in the rain goes all the way to the top, to Toronto police Chief Bill Blair and Deputy Chief Tony Warr, though it falls short of mandating charges against them.
But the report says operational responsibility lies with Supt. Mark Fenton, one of two Toronto officers who served as "incident commanders" during the G20 and had control of officers in streets. He is expected to face two charges.
Fenton's order to keep the group of protesters, bystanders and even some journalists boxed in at Queen Street West and Spadina Avenue "in a severe rain storm that included thunder and lightning was unreasonable, unnecessary and unlawful," according to the document. It violated the detainees' constitutional right against arbitrary detention and was negligent, the 276-page report says
The charges under the Police Services Act are not criminal and amount to internal discipline, which can result in docking of pay to outright dismissal. None of the out-of-town police officers brought in to help Toronto police was charged.
OIPRD director Gerry McNeilly says that following those instructions the Major Incident Command Centre (MICC) structure broke down, as the night incident commander (Fenton) launched an "autocratic" and "dysfunctional" crackdown ordering mass arrests of protesters.
Some front-line officers, according to McNeilly, ultimately disregarded Fentons orders at the kettling and let some people out of the ring of riot squad officers, including those with medical emergencies. He noted records of one officer stating of Fenton, "Hes maniacal this MICC, he's maniacal."
In addition, criminal charges were laid against two Toronto constables by Ontario's Special Investigations Unit, which probes serious injuries or deaths involving police.
The SIU charged Const. Babak Andalib-Goortani with assault with a weapon in connection with an incident at Queen's Park in which protester Adam Nobody suffered a broken cheekbone in a violent takedown captured on video. He faces a second count of assault with a weapon stemming from another incident at the same protest in which a woman was hit with a baton.
And Const. Glenn Weddell stands accused of assault causing bodily harm after 30-year-old Dorian Barton's arm was broken while he was photographing police during a protest.
