Monika,

your kind of attitude will make your 'fight for justice' much harder.

I am not trying to preach but just a thought; it may be smarter to give the benefit of the doubt and find some common ground with different voices including the drivers. That will make your argument stronger and more difficult to deny, ignore or sideline.

This does not stop you from having a readdress on the damage done where there is evidence. But if you don't have the evidence it is better to work on the solution that it does not recur.
