Ah, yes, but who's to say a homeless bum could not cure cancer? And, of course, there's really no way to know exactly how children are going to turn out; there's the whole nature/nuture as well as unforseen events that could result in a much different outcome than one might expect.

And as far as police/military risking their lives to protect-they are supposedly better trained and better armed (think about the community police departments equipped with helicopters and tanks) than the average citizen; an example being that the average citizen can't buy body armor. So, in my most humble opinion, that would seem to give police forces an edge thereby reducing the need to have enhanced punishment for their murder. Conversely, who is to say an unknown, simple housewife murdered might not have given birth in the future to the very same child that cures cancer-would not that be an argument for enhanced punishment?

I think what I was trying (unsuccessfully) to say, is that all humans have potential and all humans have someone who loves them, someone who has nurtured and interacted with them; someone who's day-to-day existance is every bit as important as the POTUS or the cop on the street.

Don't take life too seriously, you'll never get out alive.
