A motorist with more than a dozen guns - two of them loaded - and nearly 1,000 rounds of ammunition in his pickup truck was arrested at a vehicle checkpoint as he entered Los Angeles International Airport, authorities said. Phillip Dominguez of Orange was booked on suspicion of felony transportation of an assault rifle, but airport police said Friday it appears he did not intend any harm and was there to pick up someone. "He just made a very bad decision, and should not have been carrying those weapons," said airport police Sgt. Jim Holcomb. The weapons - which included 10 handguns, five rifles and an antique black-powder musket - were in containers in the back of the 47-year-old man's truck, which was stopped by airport police officers at a major entrance to the passenger terminals area, said airport spokeswoman Nancy Castles. Two of the weapons, a revolver and the musket, were loaded, Holcomb said. Dominguez's wife, Sue Dominguez, told The Associated Press that her husband planned to go target shooting at an outdoor range with a friend whom he was picking up at the airport. She said she found out about his arrest from a television news report and they later spoke on the phone.
