MACE' is an acronym for Mechanical Assisted Control Enforcement. It is a non-lethal weapon used by law enforcement officers to subdue suspects without causing serious injury. It consists of a long handle with a weighted head at the end, which can be used to strike or push a suspect in order to gain control of the situation. The use of MACE can be very emotional and upsetting for both the suspect and the officer, which is why the term IT WILL BRING YOU TO TEARS is used to describe it.
