I had a friend back in high school who became really good at committing petty larceny. He had all sorts of ways of hiding stolen merchandise, and he usually got away with it. His luck finally ran out and a store detective caught him with around $100 worth of jewelry. They charged him with petty larceny and he had to spend some time in a juvenile facility.
The problem was, his early days of petty larceny made it easier for him to take bigger risks. He was later found sitting on his neighbor's front lawn, surrounded by $4,000 in rare coins. He spent 5 years in prison for that felony crime. Petty larceny may not sound like much of a crime, but if people don't intervene and punish young criminals, it can escalate to a much more serious mindset later.
