Having established a little distance would greatly mitigate either problem
The police knew he had the kid.
This started in Bobcaygeon when his wife ran from the family home to a neighbours house. (The neighbour had recently moved to Bobcaygeon; Welcome to the neighbourhood!.)
It was originally reported she was accompanied by another woman, reported as either HER mother or a therapist.
The neighbour called 911, the wife talked to the police and told them he had the boy and an illegal handgun and gave a description of the truck.
The police quickly located the truck southbound on Sturgeon Rd
This much has been reported.
Also reported; the OPP left the wife at the neighbour's house and told her nothing for 4 hours. 3 1/2 hrs after they knew her boy was dead and husband gravely injured.
After that it is all speculation.
The OPP could have "backed off" or given the guy space
The guy had JUST kidnapped a child and had a gun. He was not acting logically. He was seemingly out of control.
The police HAD to keep eyes on the guy.
If they had "backed off" and the guy "murder suicided" the kid you'd all be screaming blue murder
If they "backed off" the guy could have done something SUPREMELY stupid and dangerous... like I dunno... get into a high speed police chase, try to kill a cop and get into losing shoot out?
People in control don't do stuff like that.
I would think you could see that this is text book case of why you would NOT 'back off" and do your best to contain the situation.
It seems to me that the OPP thought the guy was going to stop when they boxed him in.
They had him south bound on Sturgeon. With 3 road blocks, one on Sturgeon south of Pigeon Lake Rd and both ways on Pigeon Lake rd, they had him blocked in. He had no where to go. Everything in the cop's collective experience says they had the guy contained. When they get him contained, they can can work on de-escalating the situation.
The guy could have come upon the roadblock and stop and try to negotiate, BUT he choose to ram the road block and in SIU terms "USED THE VEHICLE AS A WEAPON". All the police training in the world ain't gonna change that. Police work can be messy and unpredictable.
It wasn't the police that escalated... this time.
I seems to me the guy turned onto Pigeon Lake Rd. to find a OPP car blocking the road, probably with cop "A" holding his hand up saying "HALT POLICE".
(they should stop doing that. Remember the TO cop that got cut down by a guy in a snow plow. )... but then maybe cop "A" was thinking that the guy had a kid in the truck with him, he recogocnises this the end... WTF??? HE'S TRYING TO RUN ME DOWN!
The SIU reported the cop was hurt by the truck, he wasn't shot, but if cop "A" thinks the guy is trying to kill him with his truck; it's a valid shoot.
now, why the OTHER two shot is a good question.
In my time line those two would be chasing the truck south on Sturgeon Rd or at another road block, we don't know how far back, and came across the suspect truck, smashed into a cruiser with injured cop "A" unloading his glock into the truck.
If they were right( a second or two) behind the truck all they would know is what they have heard on the radio, BLACK TRUCK KID
GUN, and coming upon a VERY dynamic scene, seeing cop "A" shoot, it would be easy to justify them shooting too.
I am not saying this situation couldn't have been handled differently, with what may have been a better outcome for all involved but the way I see it; it wasn't the OPP that wrote this story's plotline.
