You did a thing of honour there. Helping out the people was correct in my opinion, not that I've experienced something, that you experienced today. I think that the people who were in the car can protect you, if you're gonna be under questioning. Specially the woman in the car, she didn't get involved into anything at all. Escaping is stupid, because this will only make the theory, that you attacked on purpose, be taken more seriously. Still, there might be other witnesses, but I think the people from the car can describe everything. Good luck there Ozcar, hope you will be ok.
