I don't know. How many mass murderer investigations turned up instances where the killer "joked" about killing people and nobody took them serious until they did it? ChrisL said in essence that a family member of mine should be killed because of what she thinks he might do. It doesn't get more personal than that. **** her.
Nice loaded question. Let's see, "How many rapists claim the victim was asking for it?" See how that works?
How about this; "How many people joke about killing someone or beating the shit out of them and never do?" That number is very likely to be in the millions because, as you
probably know, mass murderers are relatively rare.
Example; over 310 MILLION Americans in 2013, but 28 mass murders. Should I do the math for you? (it's 0.000009%) You are, literally, more likely to be struck by lightning. Chance of being hit by lightning in a single year is 1 in 960.000 or 0.0001%.
