Many years ago the LAPD banned the use of a particular choke hold as there had been several deaths of suspects.
Watch the extended version of the opening scene in the Return of the King. Seems like it lasts forever.
Actually *Breaking Bad also has a fairly long and difficult to watch choking scene, but not manual strangulation (a bike lock and a metal post make a type of garrote.)
I tried finding it but failed, but anyway a very prolific serial killer said in an interview that he specifically has a problem with how strangling someone is portrayed as so easy. He had strangled several of his victims, and was essentially bragging about “how you have to be very strong to do it.”
