From the book Left of Bang: How the Marine Corps’ Combat Hunter Program Can Save Your Life:
* A study, which focused on the relationship between tattoos and the criminal way of life, found that criminals get tattoos for reasons such as “self-indulgence, a need for gratification, a deep commitment to delinquency and criminality and a disregard of their consequences” and concluded that tattoos endorse the criminal lifestyle.
Tattoos have been shown to be associated with high-risk behavior. Several studies have linked tattoos with “deviance, personality disorders, substance abuse, risk-taking behavior, and criminality.”163 One scholar writes, “The criminal world universally considers tattoos an inseparable part of their symbols.”
