I would still say it's circumstancial unless you have footage of her actually causing damage. As said previously, it may be an excuse to question her informally, but if denied, they're going to have difficulty proving anything. The head popping up might help but in the UK at least, if the video didn't show her actually doing the damage, I doubt it would suffice. Maybe US law might be more lax on that. She could always throw out an explanation for going around the truck - she was trying to coax out a cat to stroke it, she dropped something and it rolled under etc. Pity your neighbours ring didn't capture her causing the damage.
