OK so a way to reduce violent behavior well an easy way would be a reward system bud Getting rewarded for not being violent also a non violent community/home environment would be a good step for being less violent. A life saving procedure would be CPR !. you tap on the shoulders and see if they OK if no response 2. you put your hands in the middle of the chest area 3. you begin to push you hands down and up but don't fully move your hand off of the chest. 4. tilt the head and pinch the nose while giving rescue breaths.
