TPAC Authority?

[Haltamer]

Been watching a lot of police interceptors of late, and one thing I notice is that at the almost the very start of each pursuit, (Even when a single car only) they seem to request TPAC Authority.

Why are they going for authority before there is even an additional car on scene? surely they've no hope of putting on a TPAC with one car?

Probably more than one way to do a tpac if there are no TV cameras

I thought in that context TPAC referred to chasing them rather than trying to box them in.

Presumably the ‘pursuit’ bit of the acronym?

A pursuit has 3 potential phases;

Information gathering - when you’re behind the subject vehicle completing relevant checks, before it reacts to the presence of the police vehicle.

The below is copied direct from the guidelines;

Initial phase

This is the period of a spontaneous pursuit before tactical resolution can be considered and actioned. Pursuit trained standard/response drivers/motorcyclists with suitable vehicles may be authorised to continue by an appropriate member of staff from the control/communications room but they have no authority to take an active part in tactical resolution. Tyre deflation systems may be used in the initial phase.

Tactical phase

This is the phase of an authorised pursuit, for which appropriate resolution tactics are available. It is commenced by, or taken over by, a tactical phase trained advanced driver in a suitable vehicle, with a pursuit commander identified. Once the pursuit moves into the tactical phase, tactical options for bringing the pursuit to a conclusion will be directed by the pursuit commander.

I would have thought it getting relevant authorisation in place for later on maybe?

One thing I've always wandered is when they request this they are being given permission by the radio controller who is surely less qualified to judge then they are being at the scene and an advanced driver.

I would imagine a large part of this is that the person is independent of the situation.

Permission is given by an incident manager or pursuit manager. The operator just passes on the request. However, an operator can order a pursuit to be aborted if they believe it should be stopped.

TPAC is requested early in circumstances where it is deemed that it may be required as a tactic to safely end a pursuit. It can be requested and authorised before there are sufficient units in place to carry it out.

It means if they need to make contact later, or the chance for boxing them in comes up naturally before they'd normally go for it, they have permission.

When they ask for permission the dispatcher will be speaking to the control room inspector who has to manage incidents. Or the inspector might be talking to them directly. They'll be trained in management of jobs like this. And it's their job to risk assess, and the drivers job to inform them.

Also, some will have experience. In Durham, Kev Salter who was on interceptors works for the control room, I'd say he's well placed to manage pursuits from there.
