Consider that a large increase of the reduction of homicides is greatly influenced by the fact people don't die.
BALTIMOREThe number of U.S. homicides has been falling for two decades, but America has become no less violent.
Crime experts who attribute the drop in killings to better policing or an aging population fail to square the image of a more tranquil nation with this statistic: The reported number of people treated for gunshot attacks from 2001 to 2011 has grown by nearly half.

"Did everybody become a lousy shot all of a sudden? No," said Jim Pasco, executive director of the National Fraternal Order of Police, a union that represents about 330,000 officers. "The potential for a victim to survive a wound is greater than it was 15 years ago."
In other words, more people in the U.S. are getting shot, but doctors have gotten better at patching them up. Improved medical care doesn't account for the entire decline in homicides but experts say it is a major factor.
Emergency-room physicians who treat victims of gunshot and knife attacks say more people survive because of the spread of hospital trauma centerswhich specialize in treating severe injuriesthe increased use of helicopters to ferry patients, better training of first-responders and lessons gleaned from the battlefields of Iraq and Afghanistan.
"Our experience is we are saving many more people we didn't save even 10 years ago," said C. William Schwab, director of the Firearm and Injury Center at the University of Pennsylvania and the professor of surgery at the Hospital of the University of Pennsylvania.
