Large language models exhibit systematic vulnerabilities to adversarial attacks despite extensive safety alignment. We provide a mechanistic analysis revealing that position-dependent gradient weakening during autoregressive training creates signal decay, leading to incomplete safety learning where safety training fails to transform model preferences in later response regions fully. We introduce base-favored tokens -- vocabulary elements where base models assign higher probability than aligned models -- as computational indicators of incomplete safety learning and develop a targeted completion method that addresses undertrained regions through adaptive penalties and hybrid teacher distillation. Experimental evaluation across Llama and Qwen model families demonstrates dramatic improvements in adversarial robustness, with 48--98% reductions in attack success rates while preserving general capabilities. These results establish both a mechanistic understanding and practical solutions for fundamental limitations in safety alignment methodologies.

Raul Gastesi speaks with Fox News Digital about a bill moving through the Florida Senate that would give homeowners the right to use "reasonable force" to take down drones infringing on their privacy rights. A newly-minted law allowing Arizona law enforcement officers to shoot down drug-carrying drones along the U.S.-Mexico border has taken effect after sailing through the state's legislature with bipartisan support. HB 2733 was signed into law on April 18 and grants officers the ability to target drones suspected of carrying out illegal activity within 15 miles of the state's international border. "Cartels are increasingly using drones to survey the border to locate [U.S. Customs and Border Protection] officers' locations and to transport illegal drugs from Mexico into our state," state Rep. David Marshall, the bill's sponsor, said in a statement to Fox News Digital. "Law enforcement tools at [our] disposal will be electronic jamming devices, as well as using shotguns with bird shot to bring down these drones."

Police seized ketamine hidden inside life-size Transformer robots in Thailand. A woman who was previously caught trying to ship meth hidden in a food processing machine was trying to send the robots to Taiwan. Cambodian authorities on Friday destroyed more than seven tons of illicit drugs and the ingredients for them, as a drug-fighting official said educating people about their danger is the best way of combating the illegal trade. Some 4.1 tons of the destroyed items were drugs including heroin, marijuana, methamphetamine, ecstasy and ketamine that had been confiscated from traffickers across the country, the National Authority for Combating Drugs said. The remaining 3.2 tons were various chemicals and other ingredients used to produce illegal drugs, it said.

Japan's Finance Ministry is promoting a program to introduce artificial intelligence and other cutting-edge technology to help customs agents crack down on increased smuggling of illegal drugs. The program aims to establish the world's most advanced inspection capabilities according to a plan announced by the ministry in June last year. As part of the program, AI-based analysis will be used to sort through huge amounts of data on past cases of unlawful import activity, looking for patterns of false descriptions on such matters as price, quantity and weight of goods on import declarations. The information will help pin down importers who should be watched more closely. To prevent the importing of illegal drugs, the ministry has already started testing a prototype nuclear quadrupole resonance (NQR) device that uses AI to check X-rayed items and identify possible drug smuggling.

Have you ever looked in your rear-view mirror and watched anxiously as a police car came up behind you? I'd dare say that most of us dread such a moment. It does not necessarily mean that you are a criminal or have done anything wrong. It's the notion that the police officer can potentially pull you over, referred to as a traffic stop, which gets us nervous and on-edge. Am I doing anything wrong in my driving, you right away begin to ponder. Is there anything about my car that might spark a traffic stop, you contemplate as your mind races trying to ascertain whether you are going to get pulled over or not. If the police car opts to go around you, it usually brings you a sense of momentary relief. Thank goodness, avoided getting stopped. For some drivers, once they realize that a police car is directly behind them, they will opt to switch lanes in hopes that the police car will merely go alongside and no longer sit behind their car. I know a few drivers that the minute they spot a police car even many cars behind them, they will right away try to maneuver into a lane that will keep them from perchance having the cops directly on their tail. Why do police perform these ad hoc traffic stops? In theory, the traffic stop is intended to ensure the safety of the roadways. If you are driving in a dangerous fashion, it seems sensible that having you pulled to the side of the road might prevent you from ramming into another car or running over a pedestrian. If your car is exhibiting some adverse condition and not fully safely drivable, suppose your exhaust pipe is hanging onto the ground and dragging along, this can create a traffic hazard for you and for other cars nearby. Probably handy to have a traffic stop to inform you about the matter and make sure that you are aware of it and take care of it.

Welcome to California Inc., the weekly newsletter of the L.A. Times Business section. Pharmaceutical company Mylan is still in the news after hiking the price of life-saving EpiPens by more than 400%. But keep this in mind: Of roughly 250 million raised for and against 17 ballot measures coming before California voters in November, more than a quarter of that amount -- about 70 million -- has been contributed by deep-pocketed drug companies to defeat the Drug Price Relief Act, which would limit drug prices charged to state healthcare programs. Spending on the measure could set a state record over coming weeks. No buzz kill: New federal rules for small commercial drones go into effect Monday.
