In criminal procedure, "sweating" is a term used to describe the illegal practice of interrogating a prisoner by using threats or intimidation to force them to provide information.
This term has been going around due to the large amount of pressure and exposure on the Catholic church and there attempts to cover up and shelter the pedophiles and child molesters over the years...
