When it comes to constitutional criminal procedure, privacy, and the Fourth Amendment, it’s time to get ready for the concept of “pre-search.” Like the PreCrime police unit in the 2002 movie Minority Report, which predicted who was going to conduct criminal acts, pre-search uses technology to conduct the better part of a constitutional search before law enforcement knows what it might search for.
Since January, police in Baltimore have been testing an aerial surveillance system developed for military use in Iraq. The system records visible activity across an area as wide as thirty square miles for as much as ten hours at a time. Police can use it to work backward from an event, watching the comings and goings of people and cars to develop leads about who was involved. “Google Earth with TiVo capability,” says the founder of the company that provides this system to Baltimore.
