The constitution of the U.S is like a .police man. They protect you ,help you and give the best they can
For Example .. "As per Constitution of US, It is my right to convey my opinion in public"
Balance of power.
Yes and no, it depends in what state you live. For example if you live in states like New York, you don't have a 2nd and 4th amendment. But in freedom loving states for example Texas, Louisiana and Arizona you are guaranteed all the rights that the constitution guarantees.
an example is the US Constitution Preable
The US Constitution is both a limitation of the rights of the people (by protecting minorities, for example) and of the states.
Many people have become disillusioned with the US Constitution and political system. The protesters at the Occupy protests are a good example.
The method to change the US Constitution is to make amendments to it. This has been done many occasions. One example is the 13th amendment which abolished slavery.
There is no need for such an example or such an argument. Double Jeapordy IS abolished in the US by virtue of the US Constitution.
It is one of the checks and balances of power provided in the US Constitution.
With regards to the US Constitution, changes made are called amendments. As one important example, in 1865, the 13th amendment was made to the US Constitution to abolish slavery. The Framers of the US Constitution believed of course that Constitution would require changes as time passed, however, they were cautious about changes and the amendment process is difficult.
External influences may affect the way the Constitution is interpreted. For example, the growing unpopularity of slavery in the world led to an abolition in the US even though the Constitution implicitly recognized the existence of the practice.
