There’s a reality TV show in the U.S. where family members / friends attempt to free other family members/friends held in polygamous cults. The hazard analysis shown by the team prior to extraction beats all "cop" shows because it is closer to real life, i.e. no guns but real concerns about the chance of bodily harm, property laws and kidnapping laws.
