In the murder of Australian exchange student Christopher Lane in Oklahoma, in contrast, there is solid reason to believe that gang culture is a strong influence contributing to this senseless killing. Carmel Melouney has this article for the Herald Sun of Melbourne, Australia. James Johnson believes that his son was the intended next target:
The Herald Sun also has this article on the social media posts of the alleged killers.
"They threatened to kill my son because they are in a gang, the Crips, and were trying to get my son in it and I wouldn't let him do it.
"I told him he couldn't run with those boys. He's a little terrified."
Mr Johnson said the Crips, a predominantly African American street gang that began in Los Angeles in 1969 and had been in Duncan for the past few years.
Culture rot, the worst aspect of which is the glorification of gangs and crime, is a major contributing factor in too many young people's disastrous choices to take the wrong path and end up in prison or dead. It does not get nearly enough attention.
