****Could it be a result of the glamorization of murders on TV and in movies? ****
Indeed. Once upon a time movie theaters were governed by a ‘rating’ for kids, teens, adults.
For several years violent and sexually explicit movies have been shown on TV, easily accessible to all age groups. There are warnings, but not all parents lock in the controls.
Our kids think the movies are real life and it is almost true.
Movies and TV are just a part of what they view. Kids can find videos on YouTube, live leak, etc which will show about anything.
