The Bill of Rights is the most important part of the Constitution. It guarentees each American their basic human rights.
The First Admendment is: Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
The Second Admendment is: A well regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed.
There are "Gun Free" zones all over the U.S. these days. These places make it a crime to carry a gun onto the premises. All of these places are posted with signs that say something like "No Guns Allowed."
Could you imagine the media and political fallout, the horrendous nightmare that would accompany anyone putting up a sign on a building that said, "Only Catholics allowed" or "No free speech allowed in this establishment" or "No Mormons allowed?" Seriously, why is it ok to put up a sign to ban one Right, such as carrying a gun, and not another Right like Free Speech? Such, there is private property in play at a bunch of these places and a person can bascially do what they want on their own property.
On the other hand, all these recent National Tragedies have hapopened in these so called Gun Free Zones; Virginia Tech, The Mall Shootings, etc. The reason these tragedies can happen is that the bad guys know they are the only ones armed.
