Mantraps are physical security devices or constructions designed to entrap a human.

Historical usage [link]
Historically, mantraps were mechanical devices for catching poachers and trespassers. The devices have taken many forms, the most usual being like a large foothold trap, the steel springs being armed with teeth which met in the victim's leg. Since 1827, they have been illegal in England, except in houses between sunset and sunrise as a defence against burglars.[1]
Also, other traps such as special snares, trap netting, trapping pits, fluidizing solid matter traps[2] and cage traps could be used.
Mantraps that use deadly force are illegal in the United States, and there have been notable tort law cases where the trespasser has successfully sued the property owner for damages caused by the mantrap. As noted in the important US court case of Katko v. Briney, "the law has always placed a higher value upon human safety than upon mere rights of property."[3]

This unreferenced section requires citations to ensure verifiability. |
A man trap in modern physical security protocols refers to a small space having two sets of interlocking doors such that the first set of doors must close before the second set opens. Identification may be required for each door, sometimes even possibly different measures for each door. For example, a key may open the first door, but a personal identification number entered on a number pad opens the second. Other methods of opening doors include proximity cards or biometric devices such as fingerprint readers or iris recognition scans. Metal detectors are often built in in order to prevent entrance of people carrying weapons. Such use is particularly frequent in banks and jewellery shops. Mantraps may be configured so that when an alarm is activated, all doors lock and trap the suspect between the doors in the "dead space" or lock just one door to deny access to a secure space such as a data center or research lab.
In a lower security variation of a mantrap, banks often locate automated teller machines within the dead space between the entrance doors and the interior lobby doors to prevent ATM robbery and night walk-up robberies. Entry access by ATM card to the dead space offers additional customer protection. They are also known as air locks in the security industry.

Mantrap (snare)
A mantrap is a mechanical physical security devices for catching poachers and trespassers. They have taken many forms, the most usual being like a large foothold trap, the steel springs being armed with teeth which met in the victim's leg. Since 1827, they have been illegal in England, except in houses between sunset and sunrise as a defence against burglars.
Other traps such as special snares, trap netting, trapping pits, fluidizing solid matter traps and cage traps could be used.
Mantraps that use deadly force are illegal in the United States, and there have been notable tort law cases where the trespasser has successfully sued the property owner for damages caused by the mantrap. There is also the possibility that such traps could endanger emergency service personnel such as firefighters who must forcefully enter such buildings during emergencies. As noted in the important US court case of Katko v. Briney, "the law has always placed a higher value upon human safety than upon mere rights of property."
Mantrap (novel)
Mantrap is a 1926 novel by Sinclair Lewis. One of Lewis' two unsuccessful novels of the 1920s, the other being The Man Who Knew Coolidge. Mantrap is the story of New York lawyer Ralph Prescott's journey into the wilds of Saskatchewan, and of his adventures there. The novel spawned two separate film adaptations, Mantrap (1926), and Untamed (1940).
The novel was dedicated to American broadcaster and journalist Frazier Hunt, a friend of Lewis.
Plot
Ralph Prescott, a lawyer with the New York City firm of Beasley, Prescott, Braun and Braun, is feeling the stress and strain of the demands placed on him by city and career. With a fellow club-member, E. Wesson Woodbury, he decides to travel west into the Canadian wilderness for a vacation of fishing and canoeing. Woodbury has made the arrangements, and all that Prescott need do is show up.
Travelling by train through Winnipeg, the duo make their way to the Flambeau River, then to the former logging town of Whitewater. Although Prescott impresses his travelling companion with his handling of a surly innkeeper, the two are already finding themselves to be incompatible. Woodbury chides Prescott over his decision, for example, to carry a pillow in his gear.

Great Bash Heel
Great Bash Heel (グレート・バッシュ・ヒール Gurēto Basshu Hīru), often abbreviated to G.B.H., is a professional wrestling stable turned tag team in New Japan Pro Wrestling (NJPW). Formed by Hiroyoshi Tenzan in October 2006, G.B.H. was the top heel group in New Japan Pro Wrestling until April 2009, when the rest of the group turned on their leader, Togi Makabe, and formed a new stable named Chaos, under the leadership of Shinsuke Nakamura.
History
Formation (2006)
On October 2, 2006, Hiroyoshi Tenzan, fresh off his G1 Climax triumph and a big win over former mentor Masahiro Chono and on his way to challenging for the IWGP Heavyweight Championship, announced the formation of his first stable and named former IWGP Provisional Tag Team Champions, Togi Makabe and Shiro Koshinaka, as his first recruits. Tenzan announced that the criteria for joining his group was to "be strong, bad and cool" and that the intention of his new stable was to revive the old "beautiful New Japan". Tenzan immediately began sending out invitations to other New Japan wrestlers, such as Yuji Nagata, Manabu Nakanishi and even Makabe's and Koshinaka's blood rivals, Tomohiro Ishii and Toru Yano, to join the group, which was unofficially named Mougyu Ikka. On October 9, Tenzan failed in his attempt to regain the IWGP Heavyweight Championship from Hiroshi Tanahashi, but despite the setback, announced that his quest had only just begun. Finally, on October 15, Tenzan announced that the official name of his stable was Great Bash Heel, G.B.H., and named their goal to become the biggest heel group in New Japan history by causing "grievous bodily harm", something the group's name was also a reference to. The following day, Tenzan orchestrated a truce between the teams of Makabe and Koshinaka and Tomohiro Ishii and Toru Yano, who became the fourth and fifth member of G.B.H.
Charged GBH
Charged GBH, commonly known as GBH, are an English street punk band which was formed in 1978 by vocalist Colin Abrahall, guitarist Colin "Jock" Blyth, bassist Sean McCarthy (replaced by Ross Lomas by the time they had signed to Clay records) and Drummer Andy "Wilf" Williams. GBH were early pioneers of English street punk, often nicknamed "UK82", along with Discharge, Broken Bones, The Exploited and The Varukers. They have gone on to influence several punk rock musicians. The name GBH was inspired by then-bassist Sean McCarthy's trial for grievous bodily harm, though some fans also believe it is an acronym for "Great Britain Hardcore" and "Great Big Hair". Though the core line up of Colin, Ross and Jock has stayed the same throughout their history the drum stool has been occupied by a number of incumbents following Wilf's departure after the Midnight Madness and Beyond album and Oh No It's GBH again 12" ep. 1986 saw the arrival of German drummer Kai Reder who played on three albums and an EP (No Need To Panic, A Fridge Too Far and From Here To Reality, as well as the "Wot A Bargain" 12"), Kai was then replaced by American, Joe "Fish" Montanero for one album (Church of The Truly Warped), this was the band's last release for the Rough Justice label. The drum stool was then occupied from around 1994 by former Bomb Disneyland/Bomb Everything drummer Scott Preece, who has remained to this day and played on all releases since.
