Defending Scanners & Pat Downs

John Pistole, head of the Transportation Security Administration, says the inconvenience of body scanners and pat downs is a small price to pay for safety.

The debate over expanded screening touches on the proper balance between safety and civil liberties. Some legal experts wonder whether the TSA violates the Fourth Amendment protection against unreasonable search and seizure. Mr. Pistole is bracing for a grilling on Capitol Hill and likely legal challenges. But some critics, such as the former head of American Airlines Robert Crandall, question the TSA's methods from a security point of view. The agency treats each and every passenger as an equal terrorist threat. As a result, the vast majority of resources are devoted to where little threat exists.

  • Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.

  • "[T]o have a democracy that thrives and actually that manages to stay alive at all, you need regular citizens being able to get good, solid information," says Craig Newmark.
  • The only constructive way to deal with fake news? Support trustworthy media. In 2018, Newmark was announced as a major donor of two new media organizations, The City, which will report on New York City-area stories which may have otherwise gone unreported, and The Markup, which will report on technology.
