It appears that Shelton is not done, it appears he blames the whole system and is declaring war on it going after everyone involved with his family's case. So Rice has to stop him but Shelton is way ahead of him.
一句话评论：貌似很多人没有看懂这部电影啊。永远保持一颗柔软的心。“我是想摧毁这个腐朽的体制“——每一个小人物的烟花梦。你不给我一个说法，我就给你一个说法！。腐败的司法体系。《守法公民》续集《修法公民》：Law Amending Citizen。一部用力过度的犯罪片。如果此片有两个半小时会更完美。个体公正和群体公正的碰撞。终究还是复仇。
