Jenny, an awful lot of RMT episodes are historically, legally, scientifically, or technically illiterate. They get MANY things wrong, ALL the time. As a licensed attorney, I roll my eyes at the crime & mystery episodes' ignorance of legalities. Nevertheless, the shows are fun. I think the writers were going for a good story, and didn't bother to check their facts. This was also before the days of the internet and Google. Fact-checking was more laborious.
