the glorification of violence through the media and video games and the subsequent desensitisation to violence that occurs must have some effect.

It can sure have an influence.

The authorities hardly care about helping people int he aggregate, they are there to make money. The are operating form an ruler-dominator mindset much of the time, despite some exceptions for good-willed people who don't. There is a code to not rat on those in blue, to tolerate corruption and wrongdoings. They protect each others before ours.

Thanks for the feedback.
