This article summarizes certain "truths" about crime that are seen across numerous studies - seen so consistently, in fact, that they reveal the underlying reality of criminal behavior. If you don't feel like clicking though (though I think you should - it's a good read!), here's a quick summary:
Crime is "concentrated" in 3 ways:
Place - 5 percent of the locations in a given city account for 50 percent of that city’s crime.
People - 5 percent of the criminal offenders (not 5 percent of the "general population" mind you) in a given city commit about 50 percent of that city’s violent crime.
Time - criminal activity in crime hot spots and among chronic offenders tends to occur at night, during the weekends (Thursday night through early Sunday morning), and in the summer.
Why is this important?... take NJ, for instance... scan through the many gun bills that have been proposed over the past couple of years. Nine-nine percent focus on things that only affect legal gun owners - proposed changes to the firearm itself, or changes to permitting, increased fees, etc. Only rarely does a proposed bill address the actual realities of crime (and chronic criminality) as expressed by the 3 concentrations above. So, unless the bill is proposing a very targeted solution (either in a tough neighborhood or working with chronic offenders, etc., and again, those bills are rare), pretty much all the rest of these bills are politicized poppycock that are disconnected from reality and certain to have negligible impact (if any) on crime. (I know you already knew that! LOL. But it's always nice to see the science back up the gut instinct).
