The latest crime trends - up or down?


Just arrived: The January-June crime statistics for 2013 !

Each summer the FBI releases semi-annual results from year before crime statistics. To criminology geeks like me they are like candy. And guess what! For the 73 cities over 250,000 population crime is the same it has been for decades. Down!

But not everywhere!

DECLINING CRIME

Murder, the most reliably reported crime, is still declining. In Philadelphia murders are down -36%, New York -19%, New Orleans -20% and San Antonio -41%.

Why? In the Big Apple maybe broken windows or stop and frisk policing works? Yet both are controversial. Plus cops have been accused of cooking the books. In New Orleans I'd like to think Hollygrove's SafeGrowth program had at least some impact along with the new CeaseFire anti-gang program.

The truth is it's difficult to claim victory from programs in one place when crime falls in other places without those programs. Doing so is willful blindness.


Speaking of willful blindness, there are criminologists who claim auto crime is down due to the spread of more sophisticated security technology. They ignore that crime declined across many categories (in many countries), when security technology was absent (as in domestic violence). When crime categories plummet together, how logical is it that security technology explains auto theft declines but nothing else? 

CLIMBING CRIME

There are much more important things than crime theory-squabbles. Alarmingly, murders are climbing  in a number of cities. In Las Vegas murder was up 56% (from 32 to 50), in Indianapolis 41%, (46-65), Cincinnati 45% (22-32), Baltimore 9% (105 - 115), Memphis 7% (56-60), and Dallas 17% (62-73). Are these statistically significant or normal variations?

Either way it is troubling. In a few of those cities new police programs are already in place. Memphis uses the predictive policing program called Blue Crush. Apparently, at least with murder, it isn't working.

Are the good times over?
