The evidence he was traveling at an unsafe speed for conditions is the injured four year old child.
You seem determined to forget this in your attempts to defend a government employee.
Offer evidence or shut the hell up. You speculate about high speed, but offer nothing other than the officer's response as proof.
Sorry, that doesn't fly. So no one ever, while traveling at or under the speed limit, has ever hit anyone who stepped/ran into the street in front of them? Bull excrement.
should the cop have let the father continue to beat him? for how long?
