I presume the paramedics arrived via ambulance to render first aid. Was there any protest against taking him to the hospital, most likely in the same ambulance?

I pray the man who was injured gets well. If you're trying to prevent big machines or cars from moving -- don't assume the drivers know you're there and won't run over you.

that's really a naughty car, isn't it!

Why are they desecrating the Shabbat? They should be praying, reading or spending time with their families instead of this fanatic behavior. This behavior will only destroy them. They surely cannot believe that God is on their side of such stupid actions.
