MARKETPLACE | Marketplace Tech for Tuesday, August 18 | August 18, 2015 | Ben Johnson of Marketplace Tech spoke with Clinical Professor Susan Crawford about the nature of the NSA’s “cozy” collaboration with AT&T and other companies for data collection. Professor Crawford points out that government agencies are able to escape Fourth Amendment restrictions by working with private companies who screen and sort the data before handing it over, and AT&T’s vague criteria regarding what to pass on meant that the NSA was able to examine large swaths of customer data.
