Persistent Surveillance, Andrew Guthrie Ferguson

Persistent surveillance technologies grant police vast new investigative capabilities. The technologies both monitor targeted areas and generate databases of searchable information about people, places, and patterns that can be connected and accessed for criminal prosecutions.

In the face of this growing police surveillance, courts have struggled to make sense of a fragmented Fourth Amendment doctrine.
