Police in nothing-better-to-do shocker

Start of journey:
Bunch of coppers ticketing folk crossing clapham common, going north from Clapham South Tube, across the bit that is not a cycle path, but joins it at Windmill Lane.

End of journey:
2 more coppers rousting the various homeless folk along the Canal by the zoo.

Fuck off and stop some kid being stabbed!

Jesus Christ, how many kids were being stabbed at the time?
