Flags in Minnesota

I just read in the Wall Street Journal that Minnesota has passed a law that makes it a crime punishable by a fine of $1,000 and 90 days in jail to sell a U.S. flag made somewhere other than the U.S. Since the Supreme Court has ruled that you can't ban or at least punish flag burners, it now possible to burn a flag made in the U.S. and go to jail for selling one made in Shanghai. Ain't this a great country?
