The boys in blue, usually splashed with red.
If you commit a crime in Freedom City, the FCPD will start dispatching units to attack you, depending on how much trouble you're causing; the greater the offense, the greater the response, usually. There are three different FCPD units that will come after you, as follows:
K-9s
Robotic attack dogs. These are the most commonly seen units, as they will often be running around the city attacking stray dogs or suicide bombers.
C3-50s
The FCPD SWAT team, essentially. Ninja-like skill with stun batons means you should not try taking one on.
McBain
If McBain shows up, you're fucked. Virtually impervious to damage, even compared to other police units.
If you are killed by the FCPD, you will be sent to Panopticon Prison.
