So a guy breaks into a home and terrorizes two people, and the only consequences mentioned are six months of unpaid work and a suspended sentence? Great to be a thug in Scotland I guess.
There are a few ways to do fucked up stuff and get away with it, but they all rely on the police botching their investigation by forcing you to make a confession, searching your house without a probable cause, and basically doing anything in the build-up to the the trial that would suggest to a judge that the evidence was gathered unlawfully, even if it happened to be true.
