I deal with the worst of the worst my state has to offer, the bottom of the barrel, the psychos and the Death Row types. I do it by three simple words - approach determines response. I've had guys tell me that when they came off the gurney I was going down F***ing hard...and I asked mildly, "I didn't curse at you, why are you cursing at me?" That particular individual now regards me as one of the only ones who will actually listen to him. I've lost my cool in the past and found out it did nothing but make things worse. I've talked down disturbances with nothing but my mind and radio, and I've been in the middle of gas, punches and kicking "disturbances" when the verbal judo failed. They want to escalate and I want to deescalate, talking softly is one way IF they are still in the mood to listen. Avid profanity - it fuels what they rage on. Rule number one - never ever lie. Dealing with professional liars means like fear, they can sniff a lie. Honesty is 100% my job, which includes telling them I will use gas, I will use taser, I will use dogs, and they will not like it. They listen, because I tell the truth. I also follow through with what I say, good or bad. So how to deal with these "persons"? Quietly and professionally.
