Finishing that Granville Road fight video earns you absolutely no neighbourhood-watch qualifications. You can replay the grappling. You can decide who looks toughest. You can give your verdict with enormous confidence. At least five men appeared in the footage shared online on October 16. That gives you plenty to look at. It tells you very little about what else has happened around Kowloon.

Police have arrested two men over alleged involvement in at least six break-ins. The reported losses total HK$1.7 million across three months. For the people burgled, the trouble comes with no replay button. Something that belonged to them has gone. Knowing somebody has been arrested cannot, by itself, fix that.

The fight footage makes being informed feel wonderfully easy. Watch the clip, inspect the punches, become the district's unpaid security consultant. Burglary spoils that comfortable little routine. A street can produce a video everyone discusses while residents elsewhere are dealing with losses nobody can understand by watching it.

The arrests are welcome news. But a missing possession stays missing until somebody gets it back.
