Just wanted to say, it takes a fair amount of training to become a police officer these days - physical strength as well as emotional (which goes for army, paramedic etc), which you have to get through, just prior to being accepted for further training (at least thats what my nephew had to go through)
Like I said before though, if Zain and Kristen are able to get away with everything they have done together, to me, it will be like a Don Beech repeat (initally) , so it would be nicer to see them caught and dealt with in the first instance. If Zain changes his story though (according to the spoilers) and with Kristen holding a gun to his head, whats to say Kristen will the one to finish everything maybe?!
