I listened to the scanner audio as it was going on. Kid was dead on the sidewalk, had the bomb squad xraying him and clearing his pockets as he had what looked to be suspicious objects in them.
I get keeping the scene secure, but you rope off the area, once its deemed safe put a tent over the body, take kids out other doors not near the scene. It doesn’t take 8 hours to clear the bomb squad. If I recall it was about 2:00pm the EOD stated his pockets were safe.
Whoever made the decision to hold everyone that long needs to be questioned/investigated why. The trauma for those kids will be lifelong and holding them longer doesn’t help.
