I was pulled over for speeding by a undercover agent. Because he didn't have a citation book; he radio'd a traffic cop to come and write me a ticket. I contested the ticket; saying that the traffic cop is using the testimony from the undercover, but the undercover wasn't in court to be able to be cross examined. The judge striked the testimony and I was found innocent of the speeding ticket. By the way, I was speeding and I got away.
But does that mean everyone is guilty, but just found a way to beat the system? Who knows what really happened. All those testimonies are heresay because none actually testified what they told the police. Therefor, how can you expect it to be true if you can't prove it to be true?
There is a thin line in this system, but the system works most the time. And just because you have money, doesn't always guarantee you will beat the case. OJ is one exception; but I can give you hundreds of people with money that actually were found guilty.
Do you remember the Menendez brothers?
