I'm grateful that, as a child, I sincerely believed that all policemen were the good guys, and that the only people in prison were the bad guys. It allowed me to grow up with an image of what the system should be like; the perfect ideal that we can never achieve, but should never stop striving for. When you live your life believing that impossibility has already been achieved, it takes something massive to open your eyes.
It's never fun; a key piece of the framework that holds your worldview suddenly crumbles into dust, leaving you staring through a gaping hole into a harshly unpleasant reality. It takes guts to face up to that, and even more to write about it in such a frank and honest way.
