I worked for 23 years in the CPS in England, and all we dealt with was crime so whenever there were acts of violence I would look at the files. It may be different in other parts of the world but in the UK there was little indication that you would end up on the ground in a fight. One of the things people overlook is that when somebody gets knocked down in a fight they get up as quickly as they can, usually because they are frightened of getting kicked when they are down, or they want to kick their opponent when he is down
Unlike this guy writing I have no skin in the game I don't do jiu jitsu, but it may surprise you to learn that it was the first martial art that I studied, although probably not genuine Jiu Jitsu.anyway here is an interesting article. I was a student of James Blundell mentioned in the article and knew Bob Clarke , who passed away this year
