Most people who hear, read and or see about events like, the violence on television rarely give it a second thought. TV is just one way the mass media changes us.
People see dead people lying in groups; you see bomb destruction and horrific situations and people rarely process the whole amount of information being given to you.
We are desensitized because we are constantly being bombarded with news like this. We dismiss is rather quickly because in our minds we feel are hands are tied and we are trapped for many reasons. We might be going to a job that is demanding, have children and have many other important issues on our plates and do not have time to think about these issues. If we only heard about these issues once in a great while we then may act on those issues in a way which we would push our elected officials to act.
