Translation: "We are being subjected to atrocities but they don't meet the legal standard for genocide. The reason we are using sign language and cryptic notes to communicate this point is not only to avoid being overheard by your minders but also to prevent being 'unhelpful' to the solution that is going to be cooked up by the ever-wise United Nations."
For some reason I think Jeremiah Denton would understand the dumb show perfectly.
Navy Cross Citation
"The Navy Cross is presented to Jeremiah A. Denton, Rear Admiral, U.S. Navy, for extraordinary heroism while serving as a Prisoner of War in North Vietnam from February 1966 to February 1973.
Forced to attend a press conference for propaganda with a Japanese correspondent, Denton blinked the word "T-O-R-T-U-R-E" in Morse Code at the television camera which was immediately understood by United States Naval Intelligence.
