We do have a justice system. That system works within the system of laws set forth and written.
Actually, I'll disagree with your comment about the punishment not fitting the crime.
Reality is a lot of people don't have money, they are given a public defender, and the defendant is spit out via punishment via the "wheels of Justice".
EVERYONE knows about Reids DUI issue. Why? Because he makes news, and news sells.
Exactly how many people have been hit by a drunk driver and no ONE knows about it bceause either the palintiff or defendant wasn't "newsworth" other than you local BFE newspaper on online version of that newspaper?
Our justice system isn't perfect by far, but overall in the world, it's acatually not bad exactly due to our rights.
