Attorney General Jeff Sessions claims crime has gone up in some U.S. cities because the Obama administration was too lenient in sentencing offenders. But the facts don’t back him up, according to Marc Mauer, executive director of The Sentencing Project, in Washington. “It’s discouraging that, in the 21st century, we’re making policy decisions based on sound bites and gut instincts rather than evidence,” said Mauer. “There is no lack of evidence to show that mass incarceration has been counter-productive to public safety and devastating for low-income communities of color.”
