Just as with anyone holding authority over another, there are good railroad police and not so good railroad police. I have run into both ends of the spectrum (and in between) during my years around railroads. Some are very understanding and just trying to make sure people are safe and aware, while others assume the worst first of you and go on from there. And yes, I'm sure there's probably a class given somewhere on how to hook your fingers into your belt to make you look like a real badass. That video is a classic example. It's too bad, as it gives such a negative impression. Just like why I like police cars painted in colors and don't like ones painted in black and white, like Broderick Crawford's.
