I saw a man running down the street at i'd say casual jogging speed you might run for the bus at this type of pace)

He was a weird chap no shirt on carring a big metal pipe and hair like sideshow bob.

He was being chased by about 6 coppers none of them could get anywhere near him. he ran through the cars and then into the park.

about 1 minute later one more copper turns up clearly way behind the pace and completely knackered.

Is this normal?

Of course this was followed by 4 Police vans storming past a few minutes later. Do they send even more backup when they are embarrassed?
