This is difficult to say without sounding like I'm victim-blaming...but she made a mistake when she got out of her vehicle. NEVER get out of the vehicle in situations like this. The protesters may seem peaceful, but if mob mentality ever kicks in, you're screwed. NEVER get out of the vehicle. ESPECIALLY if you have kids in there with you. When you get out, you're leaving them defenseless.
I'll say it again... Get in my way or try to block me while I'm driving, and it won't turn out good for you. Yeah, yeah, I'll go to prison...blah, blah, blah. I'm willing to make that trade. If you're preventing me from doing what I need to do, I'm going to feel threatened, plain and simple. Blocking people driving down the road or even walking down the sidewalk is NOT protesting. Legal protesting does not give you the right to block or deter others from going about their day. So if you're not doing it legally, then you deserve whatever bad things happen to you.
