New Era

(2001-today) Builds on relationship with community to gather actionable intelligence to fight terrorism after 9/11. Agencies share information joint efforts.

3 styles of policing

Watchmen, Legalistic, Service

Watchmen

Maintain order with informal investigations, controlling illegal and disruptive behavior, "Roughing up" disruptive people, considereable use of discretion

Legalistic

Police committed to enforcing the "letter of the law" Police have a "Laissez faire" or "Hands off" approach on non illegal behaviors

how many fusions centers are there?

70 fusion centers in 37 states

Discretion and individual officer

Police agencies adapt to threats posed by terrorism, individual officers still retain a considerable amount of discretion.
