John Oliver has a bone to pick with America's criminal justice system, which he says is broken for the nation's most vulnerable people: Those who can't pay for an attorney.

"It is easy to not care about this," Oliver, host of HBO's "Last Week Tonight," said of America's over-burdened public-defender system. Then he cited statistics that indicate some part-time public defenders have just seven minutes to prepare a case. Other public defenders have Kickstarter campaigns going to pay the bills.

And he told several stories of people who admitted to a crime they didn't do (most cases never go to trial) just to get out of jail.

In case those didn't drive his point home, Oliver rewrote the arrest scenes to some cop shows to reflect the new reality of what he says is our dangerously under-resourced public defender system.
