There was no tangible difference. Violent crime in this country reached a peak in the late 1980's, and it began a downward trend in 1991. That trend continued to 2011.
The AWB ran from 1994-2004. Even many supporters admitted that there was no measurable decline attributable to it. What's more, crime continued to decline after it expired.
Sometimes it’s nice not to destroy the world for a change.
