S15·E74 Up In Smoke: Part I

DCI Meadows and DC Skase are furious when PC Jim Carver turns up drunk to give evidence in a court case - evidence which is so unreliable the judge throws the case out of court. As his colleagues begin to realise the extent of Carver's problems, Insp. Monroe decides to put him on an easy task - escorting a convoy of confiscated drugs to a Home Office depot for destruction. As Carver enjoys a sly drink with depot floorman Vernon Liggett, he accidentally mentions the convoy's destination. The next day, he and Stamp drop behind as Carver dashes out to be sick. When they catch up, the convoy is under attack from four armed men. With little regard for his own safety, Carver dashes forward and tackles one of the men, who abandon their assault, although an SO19 officer is shot during the raid. Despite his heroics that day, Carver is in trouble for breaking procedure, and it could be far worse as there could be an inquiry into how the convoy route was known.
