Hugh Pickens writes writes: "The Express reports that as a task force of 125 officers continue their search for Christopher Dorner in the rugged terrain around Big Bear, it was revealed that Dorner has become the first human target for remotely-controlled airborne drones on US soil. “The thermal imaging cameras the drones use may be our only hope of finding him," says a senior police source. "On the ground, it’s like looking for a needle in a haystack.” The use of drones was confirmed by Customs and Border Patrol spokesman Ralph DeSio, who revealed agents have been prepared for Dorner to make a dash for the Mexican border since his rampage began. “This agency has been at the forefront of domestic use of drones by law enforcement.” Dorner, who was fired from the LAPD in 2008 for lying about a fellow officer he accused of misconduct, has vowed to wreak revenge by “killing officers and their families”. According to San Bernardino County Sheriff John McMahon: "To be honest, he could be anywhere right now. Torching his own vehicle could have been a diversion to throw us off track. Anything is possible with this man.”"
