Ben Shapiro, host of the 'Daily Wire' podcast on YouTube, referred to it recently, saying:
The 1994 crime bill... it brought down crime...
The only thing the Wikipedia page says about crime reduction is in reference to the Community Oriented Policing Services (COPS) Office:
... it has been acknowledged that the COPS Office had at least a modest impact in maintaining a long period of reduction in crime that had begun in 1992, but the primary reasons for this reduction remain a topic of debate.
but the COPS provision is about funding assistance for hiring local-community police officers, which is a more benign part of the bill, not one of those parts that are widely panned today.
Also, a decrease in crime is a trend than can have multiple correlated causes other than high-level-legislated policing, trial, sentencing and incarceration policy. And there's the question of what constitutes "crime": De/criminalization of certain behaviors increases or reduces crime rates. Even without that happening, if 10 more people get murdered each year, but 20 less people are beaten up; is there "less crime"? If 5 more banks are robbed for $1 million each while 1000 less stores are robbed for $5,000 each, is there less crime?
So, my question is: What parts, if any, of the Public Law are known to have "reduced crime" significantly, and under what definition and measure of crime?
