There are a number of comments I could make, but I'll stick to these:

1. The original description of the incident does not match later descriptions and neither are consistent with the photos provided. The facts need to be determined before the rules can be applied.
2. If there was contact resulting in damage, then there should have been a protest hearing at the event. What were the facts found and decision made at that hearing?
3. I generally avoid making decisions on actual incidents without all the parties present. Small differences in the facts can completely reverse the outcome.

If someone would like to present a hypothetical situation, I'd be happy to help interpret the rules.
