I used to work in retail. The police would rarely come out for a shoplifter, even if it was £1000s of pounds.
My local village shop may have to close because of teenagers regularly shoplifting. It's just not profitable for them to stay open with the losses they have.
Looking at the bigger picture, shoplifting raids are taking place regularly in London, and all the big cities, with the people involved rarely being prosecuted.
I think that we need to take this crime much more seriously. I don't want to live in a world where there are no repercussions for bad behavior. Because where will this stop? Will burgarly and mugging start to become okay next?
