A man who has filed well over a hundred lawsuits against local small-business owners says he's an advocate for the disabled. His critics say what he does is harassment and extortion. James Farkus Cohan says he's disabled with end-stage emphysema. He sues small businesses, claiming those businesses are violating the Americans with Disabilities Act (ADA). Cohan has filed at least 161 lawsuits... Eyewitness News caught up with Cohan after his daily hike up a steep hill near his Sun Valley home. He was hiking without a wheelchair, walker or oxygen tank.
