Much of our information at this time is coming from eyewitnesses, as there's been little in the way of information from Avon and Somerset police. They have only confirmed a man has died in a fast-moving incident that was "not terror related".
That, of course, makes it very difficult to break down exactly what has happened. But firstly, if what the witnesses say is correct - it appears stopping the car was planned to some degree as armed officers were part of the team.
And secondly, again if it's true, if an individual was "shot between five and ten times", then it would appear to be based on the idea of shoot-to-kill.
This means there was some imminent threat to life and that the officer must be able to justify, under the law, that their action was reasonable force to protect themselves or others.
What we don't know is: was the person who was shot armed?
It is standard procedure for any shooting to be referred to the IPCC for investigation - and we understand the IPCC have already been informed of this incident by Avon and Somerset Police.
Listen to a more detailed excerpt from an eyewitness to the Portbury Hundred police incident.
David Ellison spoke to BBC Radio Bristol's John Darvall.
Dave Ellison says police fired 'five, six, ten' times after car pulled over near Bristol.

We have still not had formal confirmation from the police about what has happened.
The air ambulance remains at the scene.
The BBC's Jon Kay described a red car at the scene with windows smashed.
Eyewitnesses to BBC Radio Bristol earlier described police "shot five or six times, maybe ten" through the passenger window of a vehicle they had blocked in.
Police said they "anticipated the road would remain closed for some time".
The Independent Police Complaints Commission said it had been notified of an "incident" by the force.

"The air ambulance has landed.
"Motorists will not be able to access Portishead from Junction 19 of the M5.
"We anticipate the road will remain closed for some time."
