This should
outrage any thinking citizen.
We need a new policy for instances of excessive use of force by police: if any such is suspected, all officers involved must be immediately suspended, without pay, while an impartial judge, not a police "Internal Affairs Division" (since police officers too often try to "protect their own"), investigates to see whether the claim is justified. If it's not, the officer(s) can be reinstated and given back pay.
If, however, the police did use excessive force:
(1) The officer(s) involved must be criminally indicted and prosecuted for any applicable charges. In this case, it would likely be "premeditated assault with a deadly weapon," and, if, God forbid, that child dies, the charge becomes first-degree murder. If convicted, the officer(s) must then be fired, losing all pension and benefits.
(2) The officer(s) must lose any and all immunity to lawsuit and/or damages under state law, including any "homestead exemption," making it possible for the victims' families to sue them for every penny they have. Yes, leaving them and their families living under a bridge if necessary.
Perhaps knowing that there might be consequences like this will make some of these officers think and double-check their facts before deciding to play G.I. Joe. If they think these rules are too tough, well, they always have an option: They can resign and go work for a living. To paraphrase Super Chicken, "They knew the job was dangerous when they took it."
