Mr. Michael Peterson was and is instructing you children at a karate studio and I asked about his past felony charges after a background check. He was beligerent and unobtrusive to me. I never went back after that and he threaten to harm me. I would like those to be aware of what he does. I finally was able to find out he got married to another woman who is being obtrusive in a custody battle which led into them controlling little children at their house. I didn't go any further, but I am afraid for the well being of the children at their house and for those at his Karate Studio.
