Can the Vulcan nerve pinch kill someone?

Question

Although Vulcans typically aren't into unnecessary killing, would they be able to kill someone with the Vulcan nerve pinch?

Answer 1

According to the show's creator; Gene Roddenberry (writing in "The Making of Star Trek") the Vulcan Nerve Pinch works works thusly:

[The] Spock pinch [is] applied with the fingers of the right hand to the area on top of the right shoulder near the base of the neck [and] blocks blood and nerve responses to the brain [which] produces instant unconsciousness

It stands to reason that if one was blocking blood flow to the brain (sufficient to cause unconsciousness), that continuing to do so would prove deadly over time.
