ISIS Video Threatens NYC:  New York City officials confirmed the release of a new Islamic State propaganda video Thursday threatening attacks on the city, though authorities assure the public that there are no "specific threats."  Jim Michaels of USA Today reports that the video, the authenticity of which has not been verified, shows images of bombs and suicide bombers readying for an attack, with shots of Herald Square and Times Square.  The NYPD released a statement saying that the department is continuing to work with the FBI, Joint Terrorism Task Force and the entire intelligence community to ensure the safety of the city.  Many major U.S. cities, New York City included, ramped up security in the wake of Friday's massacre in Paris that killed 129 people for which the Islamic State claimed responsibility.

Officer Fatally Shot in Car, Possibly Targeted:  A Los Angeles-area police officer was fatally shot in his personal vehicle in the parking lot of the police station where he worked, and law enforcement believes he was specifically targeted.  Veronica Rocha and Richard Winton of the LA Times report that 29-year-old Downey police officer Ricardo Galvez, a five-year police veteran and former Marine, was on duty but out of uniform in his personal vehicle when he was shot late Wednesday by two suspects who first fled the scene in a vehicle, and then on foot when another officer pursued them after hearing gunfire.  Lt. John Corina of the Los Angeles County Sheriff's Department believes that Galvez knew the shooters, as detectives weren't aware of any threats toward the department or its officers prior to the shooting.  A search for the suspects continued Thursday, with three people detained so far.  Galvez is the first Downey police officer to be killed in the line of duty in nearly 35 years.  Update:  The AP reports that three young men, ages 21, 18 and 16, were arrested within hours of Galvez's shooting, in what investigators say was a botched robbery attempt.

Central American Minors Surge Again at TX Border:  Following a months-long decrease in unaccompanied alien children from Central America surging the southern border last summer, a dramatic spike in the number of arrivals has occurred recently, bringing early fall migration levels to the highest ever in at least six years.  Dylan Baddour of Chron reports that according to the U.S. Border Patrol, 7,390 unaccompanied minors, primarily from Honduras, El Salvador and Guatemala, were caught crossing the border in August and September, the most recent months with available data, representing an 85 percent increase over the same period last year.  Migration Policy Institute deputy director Marc Rosenblum credits the spike to continued and increasing violence in Central America, as well as the advent of "door-to-door" smugglers, who operate in Central American villages and offer complete trips to the U.S. for thousands of dollars.  This new network of smugglers has "totally broken down" the seasonality of migration, which used to always decline in the months of August and September.  When solo children are apprehended, they are first sent to shelters, and then placed with friends, family or foster care in the U.S.

Ex-Subway Pitchman Sentenced:  Ex-Subway spokesman Jared Fogle was sentenced Thursday in federal court to more than 15 years in prison after pleading guilty to child pornography and sex crime charges.  Fox News reports that 38-year-old father of two, who is famous for being Subway's spokesman after shedding hundreds of pounds in college eating the chain's sandwiches, agreed to plead guilty in August to one count each of traveling to engage in illicit sexual conduct with a minor and distribution and receipt of child pornography.  Fogle admittedly paid for sex with girls as young as 16 and received child pornography from the former executive director of his charity, Russell Taylor, who secretly filmed 12 minors using hidden cameras in his Indianapolis home.  Taylor has pleaded guilty to child exploitation and child pornography charges.  The 14 victims of Fogle are each receiving $100,000 in restitution.  Subway ended its relationship with Fogle following the July raid of his suburban Indianapolis home.
