Oh okay, I didn't know because I was talking about suicide risks in the first part but the last part was about being killed in the line of duty.
They say people who have suicides in the family or people close to them are the most prone to do the same thing. Don't know about that but it does seem to run in some families. Dad's suicide was the first in our family as far as I know. I did witness his father's death at age 5-6, when he fell down our basement steps while walking in front of me. I think that was an accident though. Something I've never really gotten over though.
