Where's the line between security and liberty in the United States? American police forces are now armed like the military and they use their power more often than ever. On top of that, the state has the power to potentially spy on just about everything you do.

In an hour-long special this weekend, John Stossel highlights libertarians' concerns about the tactics being used to keep Americans safe.

For instance, SWAT team raids used to be rare, only used for emergencies, but now there are almost 100 a day. Sometimes the consequences are deadly. What's behind the rise in these military-style raids?

John then heads to Florida to take a look at new, cheaper "personal" drones, which could make it easier for anyone to spy on their neighbor.

The special will also break down the controversies surrounding NSA spying, the drug war, mandatory minimum sentences and constitution-free zones.

Guests include Sen. Rand Paul (R-KY), Rep. Peter King (R-NY), Fox News legal analyst Lis Wiehl, Radley Balko, author of "Rise of the Warrior Cop," current and former SWAT officers, and many more.

Catch John Stossel's "Policing America: Security vs. Liberty" on Saturday and Sunday at 10p ET on Fox News Channel.
