This is a bait and switch really purile tactic. He was saying that a gunshot wound is more lethal than a stab wound. That isn't true, he was caught in a fabrication and he then said this vapid statement which had nothing to do with the discussion.
nobody should even entertain this nonsense.
Agreed I can stab someone twist the knife while inside of them and it can make them bleed out make the wound unclosable even if they live. If one knows where the kill spots are you can easily dispatch a person with a knife with little effort.
Though I will concede if there were men in the group his efforts may have been met with a lot more resistance and he probably may not have gotten as far.
