In this Feb. 18, 2013 photo provided by K9s4KIDS, Harris County Sheriff's Deputy John Palermo and his dog Rico meet with children at the TutorVille HUB in Houston. Schools have beefed up security, staged mock drills and added metal detectors, cameras and alarms to prevent violence. Some think teachers should be armed and the National Rifle Association wants armed police in every American school. Kristi Schiller thinks some special dogs might do the trick. She wants her charity, K9s4KIDS, to do for schools what it’s done for police departments in the U.S. - place scores of trained dogs among their ranks through the nonprofit set up in 2009.
