During the 1990's in the Texas Department of Criminal Justice, Institutional Division, a food program was initiated to feed the inmates a high protein diet. For whatever reason, the program failed. There were stories of fraud etc. and it was done away with. Some of the inmates felt that they were being used as guinea pigs, and refused to consume this meal. Here is what one inmate decided to do about it.
"Joe Green", not his real name, decided to capture the attention of those in charge of this feeding program. Joe filled several envelopes with his feces and mailed it to them. Needless to say, the recipient's were not pleased at all.
All his mail was scrutinized after this.
