DEA Chief Agrees with FBI Chief on Ferguson Effect:  The nation's top drug enforcement official echoed the sentiments of FBI Director James Comey Wednesday when he called Comey's remarks that violent crime surges in many major cities may be linked to police officers' reluctance to engage suspects as "spot on."  Kevin Johnson of USA Today reports that the chief of the Drug Enforcement Administration (DEA) Chuck Rosenberg says he believes Comey's comments were "thoughtful and measured" when he suggested that the "Ferguson effect," a term coined following civil unrest last year in Ferguson, Mo. to describe law enforcement's hesitance to do their jobs out of fear of causing similar unrest, is possibly contributing to the uptick in violence in cities across the nation, such as Baltimore, Chicago, St. Louis and Milwaukee.  Milwaukee Police Chief Edward Flynn adds that "police in cities feel like they are not being supported by the federal government," and that coupled with a general breakdown of public support for officers is affecting the way communities are being policed. 

CA Univ. Attacker Praised by ISIS:  The student who was killed by University of California Merced police after stabbing four people on campus Wednesday received praise on Twitter Thursday from ISIS, which last week released videos encouraging lone wolf stabbing attacks.  Fox News reports that the attacker, 18-year-old freshman Faisal Mohammad, was described by his roommate as a loner, and a witness said that he was "having fun" and smiling he was stabbing fellow students.  Mohammad, a computer science and engineering major, began stabbing people with a large hunting knife around the start of an 8 a.m. class before being fatally shot by pursuing campus officers, who acted quickly.  Mohammad's backpack has been detonated by police and they are in the process of testing a substance found inside.  All four stabbing victims are expected to survive. 

Drug Overdoses Kill more than Guns, Car Crashes:  The Drug Enforcement Administration announced Wednesday that drug overdose deaths are the leading cause of injury death in the United States, surpassing motor vehicle and gun deaths.  Susan Jones of CNS News reports that in 2013, the most recent year for which data is available, 46,471 Americans died as a result of drug overdoses, more than half of which were attributed to prescription painkillers and heroin.  In comparison, the Center for Disease Control and Prevention tallied motor vehicle deaths at 35,369 and firearms deaths at 33,636.  The National Drug Threat Assessment concludes that "Mexican gangs remain the greatest criminal drug threat to the United States."
