The Third Amendment
This is not considered important today, although that is largely to do with the fact that we have not had a war here in a long time. During the revolutionary war, citizens of the empire were required to quarter and feed British soldiers. This was viewed as highly offensive and in fact this amendment was more important to most people than the right to free speech.
The Third Amendment:
No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law.
When we have another war on our soil, this amendment will be important again. Some people would do this voluntarily but some people don’t want to harbor the people they view as the enemy.
