Vincent "Vinny Ocean" Palermo (born June 4, 1944) is a former American mobster who was "de facto" boss of the New Jersey DeCavalcante crime family before becoming a government witness.
 Fictional mob boss Tony Soprano, the protagonist of the HBO series "The Sopranos", is said to be based upon Palermo.
A tranquillizer gun (also spelled tranquilizer gun or tranquilliser gun), capture gun or dart gun, is a non-lethal air gun often used for incapacitating animal targets via projectile injection of anesthetic chemicals usually referred as "tranquilizers".
 These guns shoot darts with a hypodermic needle tip, filled with a dose of tranquilizer solution that is either sedative, comatosing or paralytic, which once injected will temporarily impair the target's physical function to a level that allows it to be approached and handled in an unresisting and thus safe manner.
 Tranquillizer guns have a long history of use to capture wildlife without risking serious injuries to both the hunter and the target.
 Tranquillizer darts can also be fired by crossbow or breath-powered blowgun.
Space Gun (スペースガン , Supēsu Gan ) is a first-person, shoot 'em up arcade game released by Taito in 1990.
 It was later distributed for various home games consoles in 1992, and in 2005, it was included as part of the compilation "Taito Legends" on the PlayStation 2, PC and Xbox.
 It is set aboard a crippled space station that has been overrun by hostile alien creatures; there are human crew members that the player must attempt to rescue while destroying the alien creatures.
 "Space Gun" features simulated gore, giving the player the ability to shoot limbs off the creatures while blood splatters appear on screen.
 Various weapon upgrades can be found during gameplay.
 The music from the game is featured on several commercially released compact discs.
 It was fairly well received by critics both in arcades and when released for home systems.
 It was one of only a few games that supported a light gun peripheral for some of the home systems releases.
Cyber-Lip is a horizontally scrolling, side-view platformer shoot 'em up (this combination is sometimes referred to as "run and gun") arcade game released by SNK in 1990 for the SNK Neo-Geo MVS.
 Players control Rick and/or Brook, two human veteran soldiers, who are sent by an unspecified "federal government" into combat on a last-ditch attempt to save Earth from a malfunctioning military supercomputer in charge of all military androids. Gameplay consists of battling through large amounts of enemies, collecting power-ups and defeating several end-of-stage bosses.
 This makes it comparable to the likes of "Metal Slug" or "Contra" in terms of gameplay.
Romie J. Nappi, also known as Jack Nappi, was a World War II veteran and a political fixer for the Chicago Outfit.
 He worked with Murray "The Hump" Humphreys and had powerful connections to Chicago 1st Ward bosses like Pat Marcy.
Daniel John Patrick "Danny" Greene (November 14, 1933 – October 6, 1977) was an Irish American mobster and associate of Cleveland mobster John Nardi during the gang war for the city's criminal operations during the 1970s.
 Competing gangsters set off more than 35 bombs, most attached to cars in murder attempts, many successful.
 Greene had gained power first in a local chapter of the International Longshoremen's Association, where he was elected president in the early 1960s.
 Greene pushed into Cleveland rackets and began competing with the Italian-American Mafia for control of the city.
 He set up his own group called the Celtic Club, complete with enforcers.
Rosanne Cash is the debut album of American country music artist Rosanne Cash, recorded and released in December 1978 in Germany.
 It received little notice and was never released in the United States.
 Three of its songs -- "Baby, Better Start Turnin' 'Em Down", "Take Me, Take Me" and "Anybody's Darlin' (Anything But Mine)" -- also appear on "Right or Wrong".
Alphonse Gabriel Capone ( ; ] ; January 17, 1899 – January 25, 1947), sometimes known by the nickname Scarface, was an American mobster, crime boss and businessman who attained fame during the Prohibition era as the co-founder and boss of the Chicago Outfit.
 His seven-year reign as crime boss ended when he was 33 years old.
Aladena "Jimmy the Weasel" Fratianno (November 14, 1913 – June 30, 1993) was an Italian-born American mobster originally from Cleveland, Ohio, and later acting head of the Los Angeles crime family before becoming a US government witness.
 Fratianno was the most powerful mobster to become a federal witness until Sammy "the Bull" Gravano agreed to testify against the Gambino crime family in 1991.
Murray Humphreys (20 April 1899 – November 23, 1965) (also known as The Camel or The Hump), was a Chicago mobster of Welsh descent who was the chief political and labor racketeer in the Chicago Outfit during Prohibition.
 Considered to be a ruthless but clever man, Humphreys believed in killing only as a last resort as he was known to place great trust in the corruptibility of authority figures; a favorite maxim of his was: "The difference between guilt and innocence in any court is who gets to the judge first with the most".
 But perhaps the statement that best summed up Humphreys' philosophy of life was: "Any time you become weak, you might as well die".
 Al Capone said of him, "Anybody can use a gun.
 'The Hump' can shoot if he has to, but he likes to negotiate with cash when he can".
