Mountain Sage,
I am sorry the quality of clarity at your refuge from stress has become muddied. A lot of people/students don't understand how nauseating, and far reaching, an incident like this can be. Every student at that school, Instructors included, now will have lost some face due to this "man's" poor actions. With power comes responsibility. If power is attained and not treated responsibly then the wielder himself will become CONSUMED. Eventualy those who would defend him will then to be consumed by their poor judgement. This flagrant violation of common sense was premeditated. There are no excuses. Your Instructor will suffer for keeping this "man" at his/your school.
About a year and a half ago, I was faced with a difficult task at the school I own. A high schooler who reached Black Belt through years of study at our school, injured a fellow student who is also a Black Belt. For some time before I was given the courtesy of taking over the school from my GM, I noticed this young man's attitude turning. I discussed it in passing with my GM and he said watch him closely and give him time to mature a little. I thought of this boy as a nephew to me as he was growing up and attending the school, but I started having a BAD feeling about his attitude. He started acting like he was invincible in attitude and that he had "been to the mountaintop" so to speak. I sparred him a little once in awhile to politely remind him that a badass attitude was no match for a cool head and strategy. I NEVER mistreated him. He had good techniques, but refused to listen to me coaching him how to use them effectively. Beautiful and Powerful kicks and punches, but couldn't hit the broad side of a barn, when sparring, thru sheer stubborness. One day I conducted a multiple sparring session and paired him with two 40-50 somethings in succession. Both men are top flight (Black Belt) good guys who would give the shirts off their backs to a fellow student. The youngster could not score on the first older man and got miffed when I told him to relax and alter his technique. The second older partner was also frustrating him in the next match. I turned my back to check on another match next to them and out of the corner of my eye saw this young man cut loose with 2 HARD KICKS TO THE OLDER MANS ARMS USING HIS SHINS. I jumped over to grab him, but the 3rd kick had already landed before I could stop him. The older man had a puzzled look on his face as to why this guy went off. Instead of a moderate contact match aimed at trunk and head targets with feet and hands this kid got frustrated and tried to damage this man's arms with his SHINS at FULL velocity. I made him go off to the back of the class after scolding him and tended to the other student while still teaching the rest of the class. The older man was pretty sore, but toughed it out and finished class. The other students were ashamed at what they saw and heard. After a couple of days I got phone call from the victim stating that things took a turn for the worse. He went to the doctor and found out he had a BROKEN ARM. The youngster had yet to come back. When he did I said nothing until the rest of the students had all lined up to bow in. I informed them all of the arm break and stripped this youngster of his belt in front of the rest of the school. I put a white belt on him and put him in the back with the rule of no speaking to anyone. When I spoke to his parents after class, they expressed disappointment in me and my decision. They did not care about the older mans situation. The youngster was me, me, me. I then kicked him out right then and there for life. It has been over a year and he still has not found a school that he likes or likes him. I know the other competitors/owners unbeknownst to him. I never spoke of the incident, but mentioned "attitude problems and to watch him if he trains with others".
In retrospect, I know I made the right decision. No one in my school wanted to be around him after that incident. I also was concerned that if he lost it again, one of the better Black Belts might accidently hurt HIM. Also, my viewpoint business wise was this goof was an insurance liability and he could get me and his parents sued, insurance or not. The older man could have been a jerk and sued me. He came back after the cast was off and continues to this day, luckily. He understood that I could not predict an outcome like he had experienced. I was VERY lucky. Now, word has gotten around and my school is very well known for not accepting BS or losers PERIOD! My concern for your situation, Mountainsage is that the drunken incidents mishandling will cause sensible people to connect you and the others, Instructors included, in your school with that type of idiocy. Your Instructor has in a sense turned his back on everyone, but this miscreant you mention. Not good. Not sending the right message to the miscreant, the other students and the community in which you live and socialize. Your Instructor could have BOLSTERED the school's name and the reputation of everyone in it by doing the right thing and not showing favortism. I am very sorry on your behalf. If I may suggest, think about shopping around for a plan B and C school. Think about training under a man whose decisions you can respect.
A last note. The young man I kicked out was my GM's son's BEST FRIEND. My GM was out of town and had no knowledge of what happened until he came back. As you can see, I HAD A HARD DECISION. I was met with strong approval and new found trust in my GM's eyes. I had no clue what to expect, but I knew I had to try and protect his name and the NAME OF ALL THE STUDENTS. I apologize if this is not what you wanted to hear. Just being honest.
Best of luck,
white belt
