I find it hard to believe this

Okay, we live in an age where there is a study published every 5 minutes. Some studies seem sensible, some don't. Among the latter is one based on an annual federal Bureau of Labor Statistics survey of about 7,000 young people who answered questions each year from 1997 to 2008 on a range of issues. The study claims that nearly 50 percent of black men and 40 percent of white men are arrested at least once on non-traffic-related crimes by the time they turn 23. I find that just not credible and would ask where these 7,000 young men lived. I grew up in a lower class neighborhood along with some kids who wound up as criminals. However, those who did represented less than 1% of the kids in the neighborhood; the rest of us have never been arrested although we are now much older than 23.
