You can't blame the West Indians for the horrible weather. I'd call that an act of God!
As for the police being corrupt - surely you mean inept? Corrupt suggests something much more sinister.
I agree that the (English) bloke in charge of the investigation seems to be quite clueless.
I suspect he moved to Jamaica for a cushy life, then someone got inconveniently murdered and he's had to stop spending time at the hairdressers with his luxurious quiff, and actually do some detective work!
I had to laugh yesterday at the "Police ask witnesses to come forward" headline on Ceefax.
It's all getting a bit desperate. Next they'll be saying "please can someone confess? Go on, you know you want to..."
