The crime could have been prevented if the Illegal was never let in the country...When I was stationed in the Phillipines this was a common and legitimate civil suit argument. Run over a pedestrian, a chicken, a goat or pig, or beat a thief up, etc. the lawyers sued and said if the Service man had never come to this country it never would have happened. GI, you are GUILTY! Pay up.
I experienced the same kind of thing in Turkey. One of our guys ran off the road and hit a tree. The tree was found 25% guilty for growing there. The American GI 25% wrong for hitting the tree and 50% wrong for being in Turkey.
