The winter before my junior year of high school I was running on a gravel road a few miles from my house. Around five miles into my run I got surrounded by some large, aggressive and surprisingly fast dogs. Fortunately their redneck owner was nearby. As he said 'He don't bite' the largest dog took a sizable bite out of my running shorts. I told the incompetent owners that I was okay, but in retrospect I should've at least demanded that they fork over $40 for a new pair of shorts. I don't run on that road alone anymore.
The next year, just before the beginning of my senior outdoor season a teammate and I were on an easy run after school. We passed an older guy (early 80s). He was walking in the middle of the sidewalk so we parted around him. After we passed him he yelled something after us, which we had a good laugh about.
The next day at practice the head coach called a team meeting. He demanded that whoever had pushed an old man down step forward. I immediately explained what happened, but I was too late. The old guy had called the school and said that we had pushed him to the ground. Unfortunately, he had donated some trivial sum of money to the team, so the coaches took his side.
We were banned from leaving campus until we arranged an in-person meeting with the guy to apologize. My teammate wanted to go ahead an apologize, but I, being a prideful fellow, refused to apologize for something that I didn't do.
My distance coach, however, was more understanding. She let me do my runs before school and come to practice for a few minutes after school. (At this point I was running around 60 mpw, and everyone else was running around 30 mpw)
After a while, the rest of the team got sick of doing easy and long runs on the track, and the subject of arranging an apology was rekindled. I did a bit of research about the guy, and I found out that he was a close assistant and friend of my state's KKK-member senator in the 1940's. I told my teammate this, and he lost it. He had a very loud conversation with the head coach, who immediately capitulated and allowed us to run off-campus again.
In retrospect, I should've handled it better. I should've swallowed my pride and apologized, and it was unfair to cause a punishment to be exacted on my teammates for something that I was accused of.
The moral of this is that there is no correct way to deal with bad coaches believing libelous accusations.
