Crime has never subsided as a topic for local news or prime-time detective shows. Anyone looking for reasons to fear going out of the house can find plenty. But the truth is our streets are safer than they have been in a long time.
The latest evidence came last week, when the FBI reported that in the first half of 2011, "violent crimes were down 6.4 percent, while property crimes fell 3.7 percent." Murder declined by 5.7 percent, rape by 5.1 percent, and robbery by 7.7 percent.
Six-month drops don't mean much by themselves. But this one continues an established trend. Crime peaked in 1991 and fell steadily before flattening out somewhat in the mid-2000s. But since 2006, both violent crime and property crime have plunged.
Today, your chance of being murdered is lower than it was in the late 1950s, a time of enviable peace and order. Robberies have been cut by more than half since their peak. Car thefts are about as common as they were when the Beatles first appeared on "The Ed Sullivan Show."
It's an understatement to say we didn't see this coming. Back in the 1990s, when crime was at horrendous levels, experts told us things would only get worse.
Princeton University Criminologist John Dilulio warned of "a sharp increase in the number of super crime-prone young males." Northeastern University professor James Alan Fox said the coming crime wave "will make 1995 look like the good old days."
As it happened, lawlessness had already begun to retreat. The homicide rate, which in 1991 reached a level of 9.8 murders for every 100,000 people, sunk to 5.5 in 2000. Aggravated assaults diminished by a quarter between 1991 and 2000. Burglaries declined by 42 percent.
You would think such a welcome trend couldn't last, but it has. And the crime statistics may actually understate the improvement. Despite the recent sharp decline in sexual assault, the FBI puts the forcible rape rate at three times higher than in 1960. But rape data -- unlike homicide, which usually leaves a corpse behind -- are notoriously susceptible to the willingness of victims to come forward.
Today, compared to 50 years ago, women are undoubtedly more likely to go to the cops after an attack, and cops are more likely to take them seriously. So the actual rate of rape may be far lower than it was then.
