lol, people who think the 1994 crime bill was responsible for mass incarceration are either totally clueless or total f_cking liars. Most likely, the crime prevention provisions, when combined with the urban renewal policies that began in the early-/mid-1980s and began to bear fruit by the early-1990s, plus policing reforms modeled after Hartford, Connecticut's, is what began the decline in crime.
But who cares about facts, just another thing to slam the Clintons on, right?
Here's a summary of the 1994 bill, by the way:
