Warning shots - don't believe in them, and I don't recommend their use. Here's a story of my only experience with them:
I was working the night shift on a weekend at the local ER (Emergency Room - I was an ER nurse for about 15 years) when the EMS guys brought in a patient with a GSW (Gun Shot Wound) to the upper chest. He was a big guy, really upset, but in no real distress. Even before the EMTs got him into the ER, I could hear him screaming: "I can't believe he really shot me!" The patient, of his own volition, told me he was at the local watering hole drinking beer when he noticed a "little crippled *** eyeballin' " him. The victim said that the more he thought about it, the madder he got, and he decided to beat the other guy up. The victim was reportedly smaller in size than the victim, and he used a cane to walk. As the patient crossed the bar towards his intended victim, he apparently vocalized his intent ("I tol' him I was gonna' kill him"). The intended victim produced a small caliber revolver (definitely not legal at that time in Texas) and begged the patient to let him leave peacefully. My patient said this only made him madder, and he continued his track towards his victim. By his own volition, the patient stated that the intended victim fired once in the air, then fired a round between his feet, and finally fired a round that struck him in the upper chest.
We had a new District Attorney that was going to be tough on crime, and decided to try the shooter. I was served with a subpoena to provide testimony as to what the patient had relayed to me of the "attack". I provided my testimony (this was my first time in court), and then the DA asked me: "and what do you think of this matter?", to which I replied: "I believe the patient said his intended victim fired one shot into the ceiling, and fired another shot between his feet before finally shooting the patient in the chest - correct?" The DA agreed, and I then said: "well, where I come from, those are called 'warning shots', and I believe he fired 2 to darn many". The DA got a sick look on his face as he silently turned towards the Judge. The Judge said: "Son, there are 2 things you should have learned in law school: 1) never ask a question you don't know the answer to, and 2) learn to read the person your questioning. This witness obviously has an opinion, doesn't mind sharing it, and he happens to be right. You've wasted the Court's time with this case that has no merit and should be No True Billed"
The case was subsequently dismissed.
(Note: for the lawyers and LEOs out there, please excuse me if I didn't correctly use the legal terms and concepts in my story. This actually happened, but over 30 years ago, and I am trying to relay the situation as it happened.)
