See the book and surrounding discussion of "three felonies a day". The Congressional Research Service cannot even produce an accurate count of how many federal crimes they are. Most estimates are over 100,000 different offenses. Add in state, county, municipal, further governmental subdivision crimes, etc. and it's totally impossible to know all the laws of the land.
They say ignorance of the law is no defense, but when the government can't even supply an accurate count of the number of the laws, maybe we should re-think that. We all commit a lot of crimes.
