Bit of weakness from the copper, I fear.
Why didn't he consider that the guy had 'abandoned' his car on the road, possibly unlocked, engine running etc? Could certainly have asked him to return to the vehicle, maybe do a thorough check, documents, tyres etc? Could certainly have 'distracted' him long enough and made his time a bit uncomfortable.
Not having a go at Police (I was one), so I know what I'd have done!
