Furthermore, University of Chicago professor (and co-author of the bestseller Freakonomics) SteveLevitt has noted that most proposed gun controls have minimal impact on gun crime.
Research by my University of Chicago colleague SteveLevitt and Julie Cullen of the University of California, San Diego, showed that for every homicide that occurs in a city, total population declines by 70 people.
SteveLevitt, an economist at the University of Chicago, and John Donohue, a professor of law at Stanford University, claim that women whose children would have been most likely to commit crimes as young adults instead chose to have abortions after the practice was legalised across the US in 1973.
