Coopertown Police Chief Shane Sullivan took over the department in November, becoming the 11th chief in as many years. He was hired on the heels of a series of police scandals that for a few months left Coopertown with no police at all. Years before that, a mayor was voted out of office after the local prosecutor accused him of racism and running a notorious speed trap.
Law enforcement experts say Sullivan's polygraph approach is unusual, though some departments use the devices for other purposes during the application process. Others try to root out bias in other ways. One polygraph expert warned that lie detectors can't accurately predict racism for reasons that include people's inability to recognize their own racism.
