Law enforcement advocates defend Sessions drug sentencing policies

The most complete national numbers for violent crime, from 2015, show that four cities -- Baltimore, Chicago, Washington and Milwaukee -- accounted for 20% of the overall increase, according to Ames Grawert, a counsel in the justice program at the Brennan Center.

"I think that the concentration point is not to be lost," Grawert said. "These might be cities that have decades of years in problems that they're dealing with."

Crime rates in large cities and nationally are also down significantly from high points in the 1990s, federal data shows.
