I am afraid that this is a common American attitude , a killing that you don't have to look at is not seriously a killing.
Killing a baby the day before it is born is killing a baby and killing an enemy with a remote control device is an act of war. But if it is done out of sight , we need not take it seriously.
A human being alive is the primary thing that law should be protecting, but it isn't particularly good at it.
As far as I know there isn't much of a definition of "person" or "human being " for the law to use.
According to Christian doctrine, we are all born in original sin, so forget the innocent part.
Any fool can tell a child from a fetus. You cannot see a fetus without an x ray or some other device ....
So the difference in abortion and infanticide is seeing .
A human being you can't see is not a human being.
I don't agree and I think some of the people who are playing catch to our hellfire missiles don't agree.
We may have to do something , but we should take it seriously, it isn't less than an act of war to kill from a distance and it isn't less than killing to kill in the dark.
