From the article:
“There are at least 5,000 federal criminal laws, with 10,000-300,000 regulations that can be enforced criminally. In fact, our entire criminal code has become a leviathan unto itself. In 2003, there were only 4,000 offences that carried criminal penalties. By 2013, that number had grown by 21 percent to 4,850. The code has become so big, that the Congressional Research Service and the American Bar Association simply do not have enough staff to adequately categorize every law we have on the books.”
