The Bill O Rights

The bill of rights is an excellent document, one that displays our freedoms and privileges, and even though it was written so long ago it still has so much usefulness today. The problem I though is not the fact that it is used today, but why it is used today. For example the first amendment states:
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.
Now somewhere in the middle of this clause they have found some strange things. Now in the text above me, some how, somewhere, the Supreme Court saw that the people have the right to privacy- Okay sounds fine to me- and with this privacy you have the right to an abortion…………..okay what? Apparently somewhere between the lines of this simple statement of freedoms is a long list of things I guess I just missed.
The second amendment is one most people jokingly call the NRA law:
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.
Right, that one sounds simple enough, but right now the Supreme Court is trying to decide if because of that comma after State, - they think that since we don’t have to raise a militia in a heartbeat that people should not be able to carry guns. I think it would be a good thing to not let people carry guns but what about hunters and people just trying to protect themselves, because like the old saying goes, “If Guns are outlawed, only outlaws will have guns.” I say just let them have it because they’ll get them one way or another.
The list goes on and on about how this and that is different or interpreted, but in the end it’s just like what my political science teacher use to say
“The Constitution says what 5 Supreme Court Justices say it does.”
