Guilty Rat

An incident occured this past Sunday at the Frwy that I don't really want to get into, but the repercussions has sent me into a tizzy. This incident led to me file a report to the authorities who promptly addressed the situation. The problem I'm left with is although people tell me it was the right thing to do, I feel really bad for getting this person in trouble. I'm quite certain that this person's actions wasn't intentional and no ill will was premeditated, but according to others, it was the right thing to do. But was it? Should I have let it go? Allow bygones be bygones? Hopefully the repercussions of that day's incidents will be for the good of humanity.
