AIBU to be pleased. DS was 17 yo, they tried to mug him for his trainers and coat. He is a 6ft rugby player, told them to get lost and when they pulled a knife on him, he punched one in the face and they both ran off. CCTV and witnesses mean that the shits that tried it are now being prosecuted, it turns out they targeted lots of students from the same 6th form college.
We live in a big city, but a small community, and both mum's have been complaining about how tough the police have been. I know both mum's and am completely unsympathetic.
