A student barred from wearing a varsity jacket emblazoned with the slogan "licensed to kill" to school in Union City has won his battle with authorities. Jess Crabtree, who paid $250 for the red and black jacket with the slogan and patch depicting an ax-wielding executioner, said he hoped that the incident would guarantee freedom of expression at his school. "I don't think the boy purchased the jacket with any malicious intent at all," said Joe Hamilton, principal of James Logan High School in the Alameda County city. "Although we think it's inappropriate, it's not obscene." But starting next year, Hamilton said, Logan varsity jackets will have to meet good-taste standards.
