Police departments nationwide continued to confront troubling incidents. This man was knocked unconscious by an officer working bar security. >> Howdy, sir. >> How are you, sir? >> What are we doing? >> And in Ohio, an offduty deputy working security at Walmart used a taser on a cab driver after there was a dispute about whether or not he was stopped in a fire lane. CBS News didn't look at one bad cop. They looked nationwide. Their IT team found police departments letting officers work offduty jobs, often armed, sometimes in uniform with little oversight and sometimes no body cameras. Same authority, same power. But when something goes wrong, departments say, "Oh, that was off duty." Right? Because accountability apparently clocks out before the badge does. That's not an accident. That's the system. Thin blue lies, baby.
