Brian Irons Profile is a file that can be found in Resident Evil: The Umbrella Chronicles.
This file is found, right next to the deceased police officer in Chief Irons' Office of Police station.
The chief of police for the RPD. He maintains the façade of being a warm-hearted police chief, but was accepting bribes from Umbrella to turn a blind eye to their many illegal activities in the city. When members of S.T.A.R.S. returned with reports of the mansion incident, he intentionally blocked all further attempts at investigating the matter.
His dark side is not a recent phenomenon. A little known fact about his past is that he was twice accused of domestic violence against his wife during his college years, and he avoided incarceration by agreeing to undertake psychiatric evaluation. During the events in Raccoon City, his unstable nature began to rear its ugly head again.
He locked down the police station to make sure all of his subordinates went down with him and even made a personal trophy of the mayor's dead daughter.
The localized version mentioned regarding his "dark side" that he had been accused of "domestic violence against his wife" twice during his college years. The Japanese version, however, had mentioned that the accusations were actually attempts at rape during that time. This was most likely done as an act of censorship due to the serious subject matter. This would be repeated in his bio in Resident Evil: The Darkside Chronicles.
