would I be punished too?

I have a bit of stress with my former boss at the moment! I don’t have much to do with him anymore thanks to God, since he was promoted! nevertheless, he is even worse with him in the house! he is also a person who never listens in principle, talks again and in principle never believes anything! for example, there was a driver who had a registration in his driver’s license with 12000kg! however, I knew and knew that it was about the old three-man’s license and that one had my boss didn’t believe me and hired at least two more people with such a driver’s license and let them drive with a 12-tonner! after the second driver came, I thought to myself: “I don’t give a shit, I hold my mouth! I say nothing more!” he obviously wanted to get angry! in any case the last driver was then stopped by the police and the continued journey was then forbidden! only then believed it my boss! in the fa. got my then boss first quite annoyed! to the management so far I did not say anything, that I had already warned my then superior already at the first driver! did I actually also make myself punishable, because then I kept my mouth shut or was it merely a moral passing away?
