There is no possible way in which the act could be assessed an accident because "accident" assumes both the presence of factors beyond one's control and that absent those factors, one has proceeded with all reasonable and due care, diligence, and mindfulness. Neither of those last three factors are in evidence. Those monsters, in an apparent fit of pig-macho, went willy-nilly without an apparent regard for the safety of the "scumbags" they were presumed to have been raiding. In the process the child was maimed horribly. Every single last cop with the least fragment of a finger print on that "operation" should swing publicly from a rope. No exceptions. No mercy.
