Meet Mike Chase, the Lawyer Behind @CrimeADay.

• Author: Krainin, Todd

You can get five years in federal prison for selling llama poop, according to Title 7 of the United States Code, Section 8313(a)(1)(B). Title 21, Part 139 of the Code of Federal Regulations prohibits the sale of spaghetti noodles that are improperly shaped. The Swine Health Protection Act forbids feeding a pig garbage that hasn't been cooked by a garbage cooker (requiring a garbage-cooking permit, naturally).

Criminal defense attorney Mike Chase, the man behind the popular @CrimeADay Twitter feed, has a new book out titled How to Become a Federal Criminal: An Illustrated Handbook for the Aspiring Offender (Atria Books). It chronicles government power at its most arbitrary and absurd. In late May, Reason's Todd Krainin sat down with Chase to learn the roots of his obsession with stupid laws.

A: The truth is that if somebody comes to me and says, "Is it illegal to do x?," whatever the blank is filled with, the answer is, "I don't know." I can't sign a piece of paper that says, "Hey, it's totally legal to do any particular thing," because you can't read all the laws.

I haven't gotten through all of them yet, even though I've been doing it for five years. I think people who read the book should know it's a work of humor. Don't do anything in the book. You're probably not going to get charged for selling, you know, runny ketchup. But you could. The specter of criminal liability hangs over all of us all the time.

Q: Are people even charged with these crimes?

A: It depends on which crimes you're talking about. We expect prosecutors to exercise something called "prosecutorial discretion." What that ends up meaning is that they charge mostly gun...
