I agree with you on the nature of the judiciary. In fact, the judges enable and legally codify the illegal law writing by the bureaucracy.
The bureaucracy won't be reined or controlled by the legislature. The abuse by the executive of using the bureaucracy to illegally write law is monumental (see Clinton, et al), while the history of the legislature reining in this executive abuse is completely defeaning.
if we can't trust anyone in our own government - we lose. so its all about figuring out who to trust and finding the right balance. tipping it to far towards the judiciary doesn't work - law enforcement would be hamstrung, as in the example with the wiretaps. and when you have people like Ruth Bader Ginsburg sitting on the highest court in the land, that's all I need to know to form an opinion.
