Mainline media is a business. They convey a lot of sensational material. A lot of the local crime news relies on police reports, affidavits and press releases as sources. The news doesn't accurately reflect criminal activity. There's an interesting article from The Dart Center which can serve as an aid in interpreting news coverage, and discusses the effects.
This may fall under information or legal literacy, but sometimes there is a way something is presented, then there is what actually happened. Sometimes if you turn the story around and look at it the other way, that is what actually happened.
Actually, people need to look really closely at the situation and circumstances surrounding an event. Sometimes the victim is the criminal. Who is the suspect? What line of work is he/she in? Who are their relatives? Sometimes something happens where there is a victim, and someone else gets blamed. Someone might want a story. A story can function as advertising and serve someone's interests.
Then there's the evidence: police reports can be hacked, medical records can be hacked and witnesses can be hacked. Just about anything is hackable when it comes down to it.
What can be done to improve this situation? People can demand more progressive news coverage, and repercussions from investigative reporting can be minimized.
