Homeland vs. Gangland
Law enforcement has “high speed, high tech” methods of collecting intelligence, but remember that David Berkowitz's killing spree was stopped because of a parking ticket
If American gangs didn’t exist, foreign terrorists would have to create them. Jose Padilla (Maniac Latin Disciples) reportedly offered to provide foreign terrorists with a "dirty bomb." This made it clear to law enforcement that foreign terrorists have developed a connection — and an appreciation for — what gangs can provide a foreign terrorist group.
For example, gangs can provide foreign terrorist groups with criminals that have the freedom of movement afforded US citizens. Gangs provide an established criminal network that is comfortable with the idea of committing crimes for money, and already operate and communicate in a clandestine manner.
Law enforcement has “high speed, high tech” methods of collecting intelligence. We can utilize wiretaps, and track cellular phone use. But remember that David Berkowitz's (Son of Sam) killing spree was stopped because of a parking ticket.
Finding actionable intelligence
Patrol officers and correctional officers develop and utilize confidential informants who can produce what Federal Agents call "actionable intelligence." For the cop on patrol and the correction officer working housing areas, that means making an arrest or finding contraband.
