The black market is a market run apart from the regular economy. The black market includes transactions of illegal goods or services such as drugs, prostitution, selling stolen goods, or otherwise legal goods where the parties are trying to avoid taxation, such as smuggled cigarettes. Generally, an increase in regulations and/or a decrease in the rule of law leads to an increase in black market activity.
Criminals Only Buy Firearms on the Black Market
Michael Bloomberg and Obama administration propaganda lies claim that criminals obtain their guns via the so-called "gun show loophole". This lie has been debunked by numerous interviews with criminals in jail and ex-convicts. Such interviews have shown that criminals almost exclusively purchase their illegal firearms on the black market or they steal them from law-abiding citizens often after their names, addresses and phone numbers have been published by unscrupulous liberal journalists via Freedom of Information Act requests such as happened in New York City in 2013.
