Not sure how you were raised, but I was raised with a system of law that allows bail while awaiting trial. They seem to have him on house arrest while awaiting that trial. Of all the things to be outraged per this situation, playing video games while on house arrest isn't at the top of the list.
I'll guarantee you that if you somehow found yourself on house arrest for something, you'd end up playing video games, watching television, doing crossword puzzles or reading a good book--whatever your interests and hobby preferences led you to do.
