"Investigators will pick through clues at the scene, try to establish a likely motive for the arsonist, then predict the characteristics and traits of the unknown offender as they look to make an arrest.
Timothy Huff, a former profiler with the FBI who has interviewed more than 100 convicted arsonists, said the typical profile of an arsonist is that of a white man aged between 15-25. The most common arson motivation is revenge, Huff said, with offenders seeking to harm individuals, groups, institutions or society in general."
Yeah, well--thanks a lot, arsonist! I don't care how mad you are at something, this is an incredibly selfish way to have your revenge.
