Children's battlefield

I keep trying to find any explanation for the death of a child by gunfire. There just isn't one. Didn't know she was in the home? Should have. From watching the 'swat teams' on TV, the raids are well executed plans to catch the bad guy. The 'bad' guy in California, I believe, was fired upon as he held his toddler. Who died? The toddler. This is not an attack on police personnel in general. Some how, the planning is flawed. No policeman/woman would ever want to shoot/kill a child. Some indepth, really indepth, revamping of procedures or goals is in order. The sooner, the better.......marge
