A man shot a police officer with his own Taser at Synod Inn before making his getaway on a stolen tractor, a crown court jury was told last week.
Swansea Crown Court heard that Darryl Dempsey, 24, from Eastbourne, was found to have committed a total of seven offences.
PC Dafydd Edwards was shot in the chest after he carried out a routine car search on 9 February.
Dempsey did not appear in court having been found unfit to stand trial. Sentencing has been suspended until a hospital bed can be found for him.
His accomplice, Wayne Dobson, 29, of Watermill Close, Polegate, East Sussex, pleaded guilty to six charges at an earlier hearing and was jailed for two years and nine months, for which he will serve half. He has been disqualified from driving.
On the day he was shot, PC Edwards was investigating reports of a disqualified driver driving in the area.
He parked his police car and approached the men, before being attacked.
Dobson and Dempsey then fled in a tractor they stole from a nearby farm, before taking two further vehicles and travelling to Cardigan.
The pair split up and Dempsey, of Brading Close, Eastbourne, was found nine days later in Sussex.
The jury ruled Dempsey had: made use of a firearm with intent to prevent arrest, committed assault occasioning actual bodily harm, committed two counts of aggravated vehicle taking, damaged property, taken conveyance without authority and had driven while disqualified.
Dobson had previously admitted assault causing actual bodily harm, criminal damage, aggravated vehicle taking and vehicle damage, and two counts of taking a vehicle without consent.
Judge Paul Thomas told him: “You and your co-defendant Daryl Dempsey were in Wales for reasons that are not entirely convincing, he was driving a car that he was not entitled to drive because he was disqualified.
"When a police officer on his own stopped the vehicle in order to speak to him about it, you both launched a cowardly and vicious attack on him, and he was hurt so bad that his career might have been, and might still be in jeopardy.
"I accept he (Dempsey) was the instigator but you joined in and played a role in the injury which was even greater when you deliberately stamped on his knee while he was on the floor having already been tasered.
“The officer said he feared for his life, and that was followed up by a number of blows, stamps, kneeing from one or more of you.
"You were told (by Dempsey) to get the police officer’s baton and ‘cave his head in’. Fortunately for everybody that did not happen.
"This was a sustained, vicious and cowardly attack against a police officer who was doing his job.”
