Eh... the article states the obvious.
What's more intriguing is how people still obsess over violence whether in the news, movies, music, sports, or video games for entertainment. People know we live in the most peaceful era. They just want drama in their lives as an excuse to tease others into panic.
The other thing is the article ignores what "cruel and unusual" punishment really is. Everyone is not the same. Many people would say that today's world is loaded with cruel and unusual punishment because it's noisy. That is people speak so much gibberish that it's hard to focus or relax on what you want.
