Do they have to have special FCC approval to jam or do they use the passive
(legal) block?

http://electronics.howstuffworks.com/cell-phone-jammer5.htm

In the United States, United Kingdom, Australia and many other countries,
blocking cell-phone services (as well as any other electronic transmissions) is
against the law. In the United States, cell-phone jamming is covered under the
Communications Act of 1934, which prohibits people from "willfully or
maliciously interfering with the radio communications of any station licensed
or authorized" to operate. In fact, the "manufacture, importation, sale or
offer for sale, including advertising, of devices designed to block or jam
wireless transmissions is prohibited" as well

Jamming is seen as property theft, because a private company has purchased the
rights to the radio spectrum, and jamming the spectrum is akin to stealing the
property the company has purchased. It also represents a safety hazard because
jamming blocks all calls in the area, not just the annoying ones. Jamming a
signal could block the call of a babysitter frantically trying to contact a
parent or a someone trying to call for an ambulance.

The Federal Communications Commission is charged with enforcing jamming laws.
However, the agency has not yet prosecuted anyone for cell-phone jamming. Under
the U.S. rules, fines for a first offense can range as high as $11,000 for each
violation or imprisonment for up to one year, and the device used may also be
seized and forfeited to the government.

While the law clearly prohibits using a device to actively disrupt a cell-phone
signal, there are no rules against passive cell-phone blocking. That means
using things like wallpaper or building materials embedded with metal fragments
to prevent cell-phone signals from reaching inside or outside the room. Some
buildings have designs that block radio signals by accident due to thick
concrete walls or a steel skeleton.
