Seeing as how this is a "Gun Site", I figure that the second amendment to our constitution should be put up here in the words written on the document itself.
Amendment II [Right to Bear Arms (1791)]
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
Now of course there are all sorts of court case decisions to refer to when seeing how certain laws came about and how this amendment has been interpreted, way to many for me to list here. However if you are interested in a certain idea/subject/case just contact me about it and I'll do some foot work and get back to you on the facts of the situation.
