i just wanted to add that there is more transparency, and more media coverage of killings, rapes, and everything in between then ever. Don't let these stories, although they are terribly tragic, convince you that this is a common occurrence or that there are a lot of people out there that are like this. The vast majority of people would never raise a firearm, let alone a fist to someone in order to solve a conflict. Just keep in mind that the U.S., depending on where you are is either somewhat safe to very safe. People think that our morals and our humanity is going down the tubes after these type of news stories, but i think that compared to any other period of our history, we are the most accepting people that resort to the least amount of violence. Just because we have less violence and prejudice, it doesn't mean that either have completely dissipated, nor should we expect them to ever fully dissipate, but there will always be some room for improvement.
