As someone who regularly walks her dogs in Dulwich Park, I wouldn't mind a bit of clarification. Are the areas in the middle of the park, where it's quite confusing in terms of where dogs can and can't be off lead, now going to be policed? There are several paths with 'dogs should be on lead signs' which cross over paths where dogs seem to be allowed off lead. It's very hard for dogs and owners to negotiate open areas since obviously, dogs can't read, and most quite innocently follow their noses when they're out at play. The pond area, children's play areas, and other sorts of enclosures are very easy to avoid with a well-behaved dog. I should say that I keep one of my dogs on lead everywhere in the park as she's quite mischievous, but my other one is very well-behaved, so when we get into the main part of the park, I generally let her off, and have never had any issues with her.
