I saw this mentioned the other day:

Fires are actually a flag in intelligence. Intel will seek to infiltrate fire departments, because if they can start a fire in a target area, everyone can be cleared out, including law enforcement and residents, giving the firefighters unfettered access. Fire departments tend to not be suspicious about such things or try to run counterintelligence on members, since the guys there just want to fight fires and save people and will be blind to the intel world if they are not network recruits.
