I was popping to Londis when a scally dashed out of the off-licence nearby with a crate of Foster's. I was about 10 metres away from the offy, and he ran the opposite way down the street at quite a pace. I'm not very fast and probably wouldn't have caught him, but I still feel bad for doing nothing and then going and buying my milk and bread.
What should I have done instead? Have you ever witnessed a small bit of crime? How exactly does one perform a citizen's arrest? Did I just miss the opportunity to get a nice certificate off a high-ranking policeman? Shabs and bandits?
