The petrol station cashier opened the door and walked out onto the forecourt with a can in his hands.

I assumed a customer had paid for the tin and left it in the shop but the attendant raised his hand in a menacing way. As the car behind me wheel-spun away from the pump, it all became clear.

The cashier threw the tin at the VW Golf leaving it with a fair-sized dent. “This is how they deal with fuel thieves in north London these days,” I thought to myself.

It is what happened afterwards that got me thinking about a far greater concern, however. Without stopping, the driver sped out of the exit turning left into oncoming traffic and continued to accelerate.

This was on Monday afternoon at the Esso Station in Archway Road, north London. The petrol station is on a roundabout and the driver decided to turn into four lanes of rush-hour traffic, rather than simply turn right and go with the flow. Who knows why?

Incredibly, he avoided a bus, a lorry and a van and made it to apparent safety as he disappeared out of view.

As I headed home, I wondered what a police officer would be expected to do in that situation. The thief has stolen £15 worth of petrol, hardly a priority in these days of cuts and over-stretched forces, but has risked the lives of pedestrians and other motorists afterwards. No doubt the public – and the police – would like to see this person caught and quickly, but officers pursuing could face serious consequences if this madman (or woman) mounted the pavement and hit a child while being followed.

Potentially prosecuted if you do, damned if you don’t.

Police Oracle has been covering the on-going saga of police pursuits for a while and, thanks to the government continuing to deliver meaningless drivel and little action, specialist police drivers are continuing to pursue criminals with the very realistic threat of criminal charges hanging over their heads.

This week a pair of Metropolitan Police officers were the latest to be told they could face criminal charges following the IPCC's investigation of a case which saw the driver jailed for 12 years.

I am sure you know the case. Convicted car thief Joshua Dobby, 23, was out on licence when he killed Makayah McDermott, ten, and his auntie Rosie Cooper, 34, as they went for ice cream in south London.

Officers fought to save their lives, the same bodies that Dobby stepped over as he made his escape. Following his sentencing it was confirmed Dobby had 53 convictions dating back a decade and was in the process of delivering this stolen car for cash so he could buy more drugs.

Some Police Oracle readers have correctly asked who is more culpable for this – the officers who pursued this reckless driver as he accelerated down one-way streets and through red lights, or a system that continued to release this clearly troubled man from custody every time officers arrested him? We can save that argument for another day - needless to say, we agree.

This is now an issue facing officers far too often.

In April, Greater Manchester PC Simon Folwell found himself in a similar position.

PC Folwell was pursuing 24-year-old Luke Campbell, who died after crashing into another car. The IPCC told the force to bring proceedings against the officer for gross misconduct for careless driving. GMP disagreed but was directed to open proceedings against the officer.

Try and catch a criminal in a car and potentially lose your job or, even worse, your freedom.

I live in an area that recently saw an increase in the number of nuisance motorcyclists - probably like most towns in the UK. Earlier this year neighbours and friends had clearly had enough and were moaning about the apparent lack of action.

“Where are the police?”

“Why don’t they chase them?”

“Knock them off their bikes and lock them up.”

They are just the lines I can print. I started by talking about the cuts and the falling number of officers nationally. I then explained why most of these motorcyclists do not wear helmets or removed them at the first sound of a siren and many of those I told were surprised. I was stunned they did not know.

Perhaps it suits some that so many members of the public are happy to blame the police for an apparent lack of action.

In June, the Police Federation of England and Wales sent a letter to forces warning drivers over the lack of protection the law gives them.

The staff association said officers had barely any legal rights and should not carry out any manoeuvre deemed illegal for civilian motorists.

The traffic sign safeguard is void if there is any element of risk to the public. The speed limit ‘safeguard’ is anything but as it will not stop charges of careless driving being brought.

Earlier this year the Fed also revealed more than 100 officers had been pursued over on duty driving matters during the preceding 18 months.

Tim Rogers, PFEW lead on roads policing, told us: “Legal advice has recently highlighted that police response and pursuit drivers are, in most circumstances, highly likely to fall within the definitions of careless and or dangerous driving.

“The federation has raised this matter with numerous MPs but to date the difficulties remain with our proposed draft for legislative change not yet having been progressed to a point where officers are appropriately protected.”

And last month the government was accused of not properly answering questions on the subject.

Halifax MP Holly Lynch wrote to Police Minister Nick Hurd raising concerns the law is not providing proper protection for emergency service drivers.

Mr Hurd explained the CPS says it is “very unlikely” to be deemed appropriate to proceed with a prosecution on public interest grounds against a member of the emergency services. That does not stop the IPCC recommending that charges are brought against police drivers though does it and the pressure that places on an officer's shoulders?

Then came the usual: “The government fully recognises the risks associated with pursuits,” before the reality: “Officers must be accountable to the public … for the way they reach their decisions, including potentially the prosecution of police officers for careless or dangerous driving.”

What clarity does that offer the federation or officers? None.

Moped-enabled crime continues to increase at an unprecedented rate - that could not be clearer. However, the protection offered to officers could not be more murky and that brings with it further problems.

A freedom of information request revealed that of the Met’s 32,000 police officers, more than 5,000 have been trained to carry out pursuits in the last five years. Of those, 315 had made the tactical pursuit and containment level since 2014. The shortage could be for a number of very obvious reasons, but until clarity is offered and the government commits to new regulations offering officers protection, it would not be a surprise to see the national number of police drivers fall.

Officers who engage in pursuits know how dangerous their job can be. The IPCC’s announcement this week illustrates that further obstacles could be waiting just around the corner once the pursuit is completed and the officers have apprehended the criminal.

The current legislation leaves them vulnerable and must be changed.

Let officers pursue criminals without living in fear of being pursued for doing their job.
