They showed him putting vaseline on his legs and then down the front of his shorts!!!! I thought that was a bit odd at the time, but
now we know why.....
The vaseline seems to be playing a pivotal part in this drama. Shall give it another go tonight but don't know whether can stand it til the trial, when he will obviously be uncloaked as maniacal weirdo.
(I reckon policeman is going to turn out to be abusing his wife too and she will slowly come to admit it/accept it whilst sorting other woman out.)
