If you talk to any cop, however hardened, and say, "Has anything that's ever bothered you", they'll tell you about the death of a child that they had to deal with.

What Brighton's got is a major sea port on either side, good for importing drugs, great for exporting cash, stolen cars, stolen antiques. It's got the largest number of antique shops in the UK, so it's a great place to fence stolen goods. It's got tremendous communication: you've got the sea ports, you've got the channel tunnel, you've got Gatwick Airport 25 minutes away, and London's 50 minutes away by train. So all these escape routes... Which is what villains like.

I think the police are a major part of the glue that holds civilised life together. They're not highly paid.

The world is changing and people don't like change.

If you and I took a walk down a shopping street in Jo'burg or Cape Town or London, we see two guys looking in a shop window, we think, "Oh, they're wondering what they're going to buy." A cop looks at them and thinks, "Why are they standing there? Are they doing a drug deal? Are they going to mug someone? Are they going to rob the shop?"

Almost every officer is going to put their life on the line at some point in their career.

There's a difference between what I call a dumb ghost and a smart ghost. The smart ghost is Hamlet's father - you know, he says, "Get revenge, my son!" That's incredibly rare. It's much more the grey lady in the same place everyday, moving across the floor.
