Anchorage Police Department Detective Glen Klinkhart recently retired from APD after 17 years on the force, but he’s hardly kicking back. Klinkhart helped launch the cyber crimes unit at APD a decade ago. Now, five full-time officers work not only on computer forensics but are online catching child predators. Moreover, he’s written a new book to aid parents in keeping their kids safe on line. He says the Internet has allowed those with ill intent to have access to children and communicate with them, but it’s also lets law enforcement have access too. Klinkhart says his book gives an overview of the Internet and also gets into specifics parents should know about.
