Forensic Firearm Examination
Forensic firearm examination is the forensic process of examining the characteristics of firearms or bullets left behind at a crime scene. Specialists in this field try to link bullets to weapons and weapons to individuals. They can raise and record obliterated serial numbers in an attempt to find the registered owner of a weapon and look for fingerprints on a weapon and cartridges. By examining unique striations impressed into a bullet from the barrel of a gun, expended ammunition can be linked back to a specific weapon. These striations are due to the rifling inside the barrels of firearms. Rifling spins the bullet when it is fired out of the barrel to improve precision. Although bullet striations are individualized unique evidence, microscopic striations in the barrel of the weapon are subject to change slightly, after each round that is fired. For this reason, forensic ballistics examiners may not fire more than five shots from a weapon found at a scene. Known exemplars ta ...

Forensic
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals.

Rum-running
Rum-running or bootlegging is the illegal business of smuggling alcoholic beverages where such transportation is forbidden by law. Smuggling usually takes place to circumvent taxation or prohibition laws within a particular jurisdiction. The term ''rum-running'' is more commonly applied to smuggling over water; ''bootlegging'' is applied to smuggling over land. It is believed that the term ''bootlegging'' originated during the American Civil War, when soldiers would sneak liquor into army camps by concealing pint bottles within their boots or beneath their trouser legs. Also, according to the PBS documentary ''Prohibition'', the term ''bootlegging'' was popularized when thousands of city dwellers sold liquor from flasks they kept in their boot legs all across major cities and rural areas. The term ''rum-running'' was current by 1916, and was used during the Prohibition era in the United States (1920–1933), when ships from Bimini in the western Bahamas transported cheap Car ...

Cyanoacrylate
Cyanoacrylates are a family of strong fast-acting adhesives with industrial, medical, and household uses. They are derived from ethyl cyanoacrylate and related esters. The cyanoacrylate group in the monomer rapidly polymerizes in the presence of water to form long, strong chains. They have some minor toxicity. Specific cyanoacrylates include methyl 2-cyanoacrylate (MCA), ethyl 2-cyanoacrylate (ECA, commonly sold under trade names such as "Super Glue" and "Krazy Glue", or Toagosei), ''n''-butyl cyanoacrylate (n-BCA), octyl cyanoacrylate, and 2-octyl cyanoacrylate (used in medical, veterinary and first aid applications). Octyl cyanoacrylate was developed to address toxicity concerns and to reduce skin irritation and allergic response. Cyanoacrylate adhesives are sometimes known generically as instant glues, power glues or superglues. The abbreviation "CA" is commonly used for industrial grade cyanoacrylate. Development The original patent for cyanoacrylate was filed in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fingerprint
A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers. Human fingerprints are detailed, nearly unique, difficult to alter, and durable over the life of an individual, making them suitable as long-term markers of human identity. They may be employed by police or other authorities to identify individuals who wish to conceal their identity, or to identify people who are incapacitated or deceased and ...

Serial Number
A serial number is a unique identifier assigned incrementally or sequentially to an item, to ''uniquely'' identify it. Serial numbers need not be strictly numerical. They may contain letters and other typographical symbols, or may consist entirely of a character string. Applications of serial numbering Serial numbers identify otherwise identical individual units, thereby serving various practical uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected. Some items with serial numbers are automobiles, firearms, electronics, and appliances. Smartphones and other Smar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pistol Serial Number
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict laws and regulations governing their manufa ...

Thompson Submachine Gun
The Thompson submachine gun (also known as the "Tommy Gun", "Chicago Typewriter", "Chicago Piano", “Trench Sweeper” or "Trench Broom") is a blowback-operated, air-cooled, magazine-fed selective-fire submachine gun, invented by United States Army Brigadier general John T. Thompson in 1918. It was originally designed to break the stalemate of trench warfare of World War I, but was not finished until after the war ended. The Thompson saw early use by the United States Marine Corps during the Banana Wars, the United States Postal Inspection Service, the Irish Republican Army, the Republic of China, and the FBI (following the Kansas City Massacre). The weapon was also sold to the general public. Because it could be obtained so easily, the Thompson became notorious during the Prohibition era as the signature weapon of various organized crime syndicates in the United States in the 1920s. It was a common sight in the media at the time, and was used by both law enforcement off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

North Side Gang
The North Side Gang, also known as the North Side Mob, was an Irish-Polish-American criminal organization within Chicago during the Prohibition era from the early 1920s to the mid-1930s. It was the principal rival of the South Side Gang, also known as the Chicago Outfit, the crime syndicate of Italian-Americans Johnny Torrio and Al Capone. History of the North Side Gang Early history Like many other Chicago-based Prohibition gangs, the North Side Gang originated from the Market Street Gang, one of many street gangs in Chicago at the turn of the 20th century. The Market Street Gang was made up of pickpockets, sneak thieves and labor sluggers working in the 42nd and 43rd Wards. The gang especially distinguished itself during the newspaper "Circulation Wars" of the early 1910s between the ''Chicago Examiner'' and the ''Chicago Tribune''. It was during the Circulation Wars that future North Side leader Dean O'Banion, then a member of the juvenile satellite ''Little Hel ...

Al Capone
Alphonse Gabriel Capone (; January 17, 1899 – January 25, 1947), sometimes known by the nickname "Scarface", was an American gangster and businessman who attained notoriety during the Prohibition era as the co-founder and boss of the Chicago Outfit. His seven-year reign as a crime boss ended when he went to prison at the age of 33. Capone was born in New York City in 1899 to Italian immigrants. He joined the Five Points Gang as a teenager and became a bouncer in organized crime premises such as brothels. In his early twenties, he moved to Chicago and became a bodyguard and trusted factotum for Johnny Torrio, head of a criminal syndicate that illegally supplied alcohol—the forerunner of the Outfit—and was politically protected through the Unione Siciliana. A conflict with the North Side Gang was instrumental in Capone's rise and fall. Torrio went into retirement after North Side gunmen almost killed him, handing control to Capone. Capone expanded the bootlegg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
