Republic member worlds are required to maintain civilian law enforcement organizations, overseen by their planetary governments instead of the Galactic Senate. Coruscant Security is one of the oldest planetary police forces in the Republic and has a reputation for effectiveness, diversity and (on the whole) positive relations with Coruscant's population.
The Sacking of Coruscant took a toll on Coruscant Security‒both in lives lost and burnout as years of rebuilding, riot control and military intervention followed. The rise of major criminal syndicates on Coruscant has embittered many young recruits, and frustrated veterans who were trained to track and arrest individuals, not fight block by block to reclaim territory from gangs.
Some say that unless Coruscant Security is given quasi-military training and heavy equipment, it will eventually be overwhelmed by the planet's problems. Few security officers favor such extreme measures, however‒they joined the force to keep the peace, not to fight a war in the streets of the planet they love.
