they are knocking over cash machines with 6 of them for a few thousand euros hardly the brightest criminals in the book, usually professional theives would want a bigger return especially with so many people. so reasonable assumption they arent professionals and hence CHAVs having a go and surprise surprise fucking it up.
just what ive seen in reports in the news on dozens of times with joyriders killed fleeing police, criminals killed etc, CHAVs getting stabbed and shit. its always the same lines or similar ones spouted. maybe you could argue the parent is deluded or just naive.

let me guess, they wernt CHAVs, they were good lads who were just "misunderstood", "the world was out to get them", "police picked on them" etc etc etc etc. Yeah fucking right.
