Not only that, but when you consider that for the last three days, and ESPECIALLY New Year's Eve day, much of Northern California, especially the area near San Ramon, was flooded and in some places without power, with mudslides in the 680 area (where San Ramon is located), those children could have been left without power, which could have put their lives in danger.

They should be pelted with rotten eggs at their perp walk.
