Use of a public letter for a performance piece - legality?

The letter by Dan Turner about his son Brock Turner has been widely covered by the news media. Does anyone have any advice as far as using this letter in a performance piece? Is it now in the public realm? http://www.huffingtonpost.com/entry/brock-turner-dad-letter-is-rape-culture-in-a-nutshell_us_57555bace4b0ed593f14cb30

No. It is still his property and, short of a quote in a fair-use context, you will need his permission (or the copyright holder's if it belongs to a publication) to make expensive use of it.

Max, how did the different news publications use it? I would doubt he would have given permission, right?

Max I see that the Huffington Post says that the whole letter is Document Cloud. What does this mean? I assume that anyone can read it, I wonder if he wanted this? Now if anyone can read it, can it be recited in a performance, or use a line from it? What is the legal nuances in this situation? How did someone put this on Document Cloud, was this legal?

Why don't you email him and ask him? If he wants it to be in the public domain, he will give you permission, and you are in the clear.

You need an entertainment lawyer. Don't decide based on MOL responses.
