A suspect in the killing of three Baton Rouge police officers was reportedly a student at the University of Alabama. Lawmen shot Gavin Long to death following an ambush. Multiple news reports are quoting the University of Alabama’s website that Long was on the Dean’s list at the Tuscaloosa campus. The suspect was reportedly enrolled at the Tuscaloosa campus for one semester in 2012. Three others police officers were wounded in the attack, one critically. The Associated Press reports two other "persons of interest" are being questioned. The Baton Rouge shooting follows the deaths of five Dallas Police officers. President Barack Obama is calling on Americans to lower avoid "overheated" rhetoric and focus on unifying words. Obama says that the shooting and other recent incidents in Texas and elsewhere come just before the Republican and Democratic conventions are set to begin. He says that's a time when rhetoric tends to get hotter than usual. Obama says the U.S. doesn't need "careless accusations" intended to score points but should instead try to "temper our words." He says attacks like the one in Baton Rouge are happening far too often and constitute an attack on the rule of law.
