".....They had to assess the risk but did they include the risk of flight from the intersection in any direction ? ....."

The cops on the ground wanted to stop him (ram him)
The cops controlling the incident in their air conditioned office wouldn't let them or their procedures wouldn't allow them to make the call to ram the vehicle.

Not the coppers fault on the ground.

Will a coroner find that Police did not consider the risk of flight from the intersection?

Most likely.
