Crimes that shook Britain is een Brits misdaad documentaireprogramma van de zender Channel 5. De serie ging in première op 20 september 2008.
Documentaireserie waarbij de vreselijkste moorden in Groot-Brittannië besproken worden met mensen die het dichtste bij de misdaad stonden. Door middel van reconstructies, gesprekken en archiefmateriaal worden in deze serie misdaden en de misdadigers onderzocht. Sommige van deze misdaden hadden tot gevolg dat de Britse wet op belangrijke punten aangepast is.
In this special episode, we focus on those criminals who have been brought to justice for one crime only to be released to commit further terrible acts. We speak to legal professionals to discover if the system is at fault or have these killers exploited legal loopholes. We talk to victims and relatives of killers who preyed on their loved ones – if the perpetrators had been kept inside – would their loved ones still be alive? And we discuss with campaigners what can be done to ensure the justice system can both rehabilitate but also ensure our safety.
