How can the American legal system justify itself morally if it jeopardizes, through its own rules, the right of law-abiding citizens to personal peace and security?

I need help answering this question. It is an assignment for my American National Government class. I have to write 2-4 page essay on this question and I am stuck.

Thank you

Umm, denial, rationalization, corruption at all levels, things along these lines... then write about the effects that each of these problems creates and how it eats away at the ability of those in the legal system to care about personal rights any more.
