Law Abiding Citizen -- Film Review

In "Law Abiding Citizen," a sociopath goes on a rampage, killing major officials in Philadelphia and holding the entire city hostage. He essentially is a character elevated out of the ranks of horror films who instead of killing teenagers reacting to hormones or other socio-biological imperatives destroys adults reacting to career dictates. As the title insists, this is a law-abiding citizen who is irate with a justice "system" that allowed one of the killers of his wife and daughter to get off with a light sentence.
