Bill Maher Compares Police Unions To The Catholic Church On 'Real Time'

Bill Maher doesn't understand why American police are "infallible."

On "Real Time with Bill Maher" Friday night, the host compared police unions to the Catholic Church, saying both have an infrastructure that has historically protected members who abuse power.

"In the Catholic Church, of course not every priest was a pedophile," Maher said. "But the institution covered up for the pedophiles. And this is what I see [with the police]."

Elsewhere in the episode, Maher spoke about Sen. Bernie Sanders' announced candidacy for president, and interviewed Nobel Prize-winning economist Joseph Stiglitz about the "opportunity cost" of the Iraq War.
