At the NYPD, a judge doesn't need to sign off on opening up an investigation into a mosque as a terrorism organization. The oversight is internal.

We have institutionalized a drone program where the oversight is almost completely internalized.

A highway sign used to welcome people to New Haven, birthplace of President George W. Bush. But it was vandalized so much, it was finally taken down for good.

It's a social contract we make. We're willing to give up certain things. We give you the right to tax us. We give you the right to lock us up. We give you the right to put us on surveillance, search our homes, whatever and, in exchange, we get a functioning society that keeps us relatively safe, and that's the tradeoff we make.

When you look at the big issues post-9/11 in the United States, whether it's water boarding, warantless wire tapping, surveillance, Gitmo, black sites rendition, all of those have been legal. Nobody has gone to jail for those programs.

We interviewed many, many men and women from the NYPD and the NYPD Intelligence Division, specifically, and they're really good, dedicated people who want to keep the city safe.
