When others "know" best

It seems like there is always one in the crowd who happens to know what is best. Whether they think they have a private line to God or that they are obviously more spiritual than you. People don't like to feel challenged whether it is personally or positionally. If they think they are right than you have to have a rock solid means of showing them otherwise. Here Peter ran into a bunch who just knew that he was out breaking the law, but Peter had a solid defense already in place.
