I had seen the first lecture before, but not the second one. Great post. But it does remind me of some very unpleasant memories. I had to talk to the investigators when I was 15, then again at 18, and another time at 20.
I took it in the ass the first time, because I was wouldn't rat on the people with me and I was too young to defend myself in that type of situation. The next two times I stood my ground and made it out without anything sticking, but the city police made sure to make my life hell afterwards.
