"Three Felonies a Day" is a recent book which addresses this issue, and how the average adult in the United States commits three crimes which carry at least the possibility of jail time per day (on average).[1] There are tens of thousands of these offenses, and it is impossible to know all which may apply to you; even if a citizen makes an affirmative action to learn, there is no comprehensive list. Even more troubling is that many of these vague, and hard-to-find crimes do not require mens rea.
TL;DR: the examples available in the Amazon excerpts from that book are all felonies which the "average adult" would not be involved in, certainly not multiple times a day. (Unless you lead a very eventful life.)
