thank you for the excellent presentation and photo comparisons

The 'F' actually stands for "Freedom"

I realized that after sending in the post. Too late!

Anyway, the FOIA is indeed a Federal law. Right?

I believe it came about in the aftermath of Nixon's Watergate mess, with near impeachment averted by his resignation. Congress wrote the law. Presumably, President Ford signed it into effect.

These websites as well as a whole host of others details non-federal uses of the FOIA:

One of the links goes to the US Postal Service. I couldn't find anything about non-Federal uses of the FOIA there, but there is lots about how to file an FOIA request.

The other link needs repair in your post, but the underlying site is obvious in it. I went out there, and found the section that you probably meant to link to. Here it is, with a comment from me below it:

7. Use The Freedom of Information Act.

There’s a powerful state law on the books called the South Carolina Freedom of Information Act (FOIA), and this can be your key to the doors of government. FOIA’s basic purpose is to ensure that the business of government is done out in the open. It requires public notice of all meetings of government bodies, gives the public the right to attend those meetings, and makes government documents and records available for review. Find out when the meetings are and start attending some of them. You will learn a lot.

You can also file an “FOIA request” and obtain all of the documents relating to a particular project or issue. There are some exemptions, but the burden is on the government to justify them. FOIA is easy to use. Send a letter (certified is best) and simply say: “Pursuant to the South Carolina Freedom of Information Act, I hereby request all documents, written materials and communications of any nature (including e-mail messages) relating in any way to [describe the issue or project you are concerned about].” The government has to respond in 15 days. They can charge you for reviewing and copying the documents, but you also have the right to go to their office and review the materials and decide then what you want to copy. I am astonished at how rarely citizens exercise their rights under FOIA. It can provide a wonderful window into the world of government decision-making. Use it!

I gather from this that South Carolina, at least, has its own FOIA.

Folks interested in 9-11 truth should investigate their own states for the same. Does New York have an FOIA?

Where do you get that the F in FOIA (Freedom Of Information Act) stands for Federal? Im not sure if it only applies to Federal agencies and Im missing something but I am 100% sure the F stands for Freedom not Federal. Im not calling you out just trying to learn something.

“No nation could preserve its freedom in the midst of continual warfare.”
-- President James Madison

It stands for Freedom, obviously. My error.

A poster above gives links for instances of it being used in non-Federal situations. It will be good to study those links, since we may be able to make use of it? one hopes.
