Oh please. I’ve taught hundreds of 11 year olds. Even the biggest ones are no way any threat to you.
Its an ignorant kid shoplifting some snacks at a food store that needs a good talking to. No need for any violence or risk of injury/death
You have no idea WHAT she was stealing, so don't assume what it was!
You can't "talk to" a kid who is running away, nor one who is hitting/punching, whatever else she was doing to the cop/s!
You don't have any kids do you.
During some training, I was hit with a taser. It hurt and I couldn’t do anything but fall down. I was over in seconds and I was fine. Its perfect to stop someone without having to use more force.
Tackling someone is more dangerous to the perp and to the cop. I don’t know if it was justified in this circumstance without more accurate facts, but at worse it was not good judgement.
