Why the people are loosing their faith on govt. as well as on law and order.?:
Actually you have it wrong.  The justice system developed and practiced in the United States is the best that has developed in mankind in all of history so far.  It is far from perfect.  It is flawed.  It is human.  It is still the best we have come up with so far.  No matter what media may claim and promote, it is getting better all the time, not worse.  Because people do better and want better, we will become better for ourselves and our children.
