Was it really worth the risk to life and the huge cost of destruction (to the tractor and the public-funded police vehicle to intervene like that? What a waste.
Gut feeling says no, but I don't know if he'd hit any cars along the way or not. Most likely no, because a tall narrow heavy vehicle doesn't stay upright at speed by hitting things to the side, but none of the reports I've seen (and honestly I haven't looked into the background of this event!) have mentioned "why were they chasing him in the first place"?
IMO you cause a crash to stop a chase if one or more of
- the suspect is 'armed & dangerous' (like, weapons - guns - and has used them during the event)
- there's a real chance that they could get away and disappear
- you don't know who they are to find them later
- they're causing a mess and you can't stop them any other way
Possibly he did the last, but they definitely knew who he was, a big tractor isn't going to disappear (follow at a reasonable distance and wait for him to stop, no he's not going to go for 12h, probably was going back to the farm, even if it was all day it would still be cheaper than one wrecked car)
You don't cause a crash just because he won't stop, or you'd tip that telehandler with the 12-year-old.
My guess is that this is typical police overreach, but I'm waiting with bated breath to hear what good reasons they've got for this.
