The garrote is a very interesting device that has a history that goes back centuries in time. It has been used in torture, in carrying out death sentences, and in sex games involving EA. It is interesting to note the dichotomy that exists in its use as a device to torture and a device to carry out a death sentence. For the latter purpose, it was known as being more humane than hanging, as when a garrote is properly applied and used, death happens very quickly. Much more so than hanging.
IMO and what sticks out to me in this case, is that there were clear indications of SA which points to the use of the garrote in respect to that aspect. The question is of course, was it used as a device in a sex game or was it used to stage the scene to imply that. I'd be curious to know how prevalent the use of a garrote was at that time in sex games. It's also worthy to note that JR when in the Navy was stationed in the Philippines, where the garrote holds a prominent place in Philippine history.
