You seem to believe that going 28 in a 30 and still hitting a child or 33 in a 35 while hitting a child is acceptable.

Not acceptable, but it happens. The ultimate part at fault is the guardian of the child who let them wander into traffic.

No, the party at fault is the party who strikes the child.

The child was crossing the street while under supervision of an adult.

The government employee struck the child.
