What solution? Do we have any evidence that when another police agency investigates such things that the conclusions are different? It already happens, some PD will have an incident that is investigated by the Sheriff or state police. And yet, in those cases, we see the same thing... everyone's cleared of wrong-doing, and maybe some mandated "use of force" training. It's bizarre and depressing.
