Flying over the runway is illegal?

I could see flyovers being illegal under two FARs - minimum safe
altitude, as well as careless and reckless. Regardless of legality,
they are totally unnecessary and unsafe. The outcome of this flight
demonstrates that point.

They aren't unsafe any more than any other aspect of flying is unsafe.
They may or may not be necessary, all depends on the circumstances.
They are necessary if you are inspecting a field that is short, soft
and/or unknown to you as part of your pre-landing activities. Many
flight instruction guides specifically recommend this in these cases.
