These are just land mines, whats to stop someone from removing the sign or relocating these things to a more populated area? Like a school playground.
You are right. And, the thing that deters people from doing this is their fear of prison.
Now, despite the potential for giving the criminals a short-term way out...
1. Government prosecution of people is most often done without correct due process. Because of this, judgments are void judgments, and can be vacated.
2. Most of the time Government gets away with faulty due process because of the ignorance of the people.
3. Government strengthens their faulty due process by getting people to hire attorneys. This makes the people wards of the court, because by law and contract an attorney is an officer of the court, and owes much more allegiance responsibility to the court than he does to his client.
The fact is, the American Government has little strength over the common man/woman when they have knowledge of their strength as man/woman.
But, if there were man/woman strength in use in the courts all over the place, the criminal wouldn't be stuck in prison for 20 years. He would be executed... in almost all cases where he cause death or dismemberment.
The reason the courts like it the way they do, they can then play the part of the criminal without fear of death.
