Biography
for|The practice of isolating prisoners|Solitary confinementotheruses|Lockdown (disambiguation)There are several definitions for the term lockdown , the most common of which pertains to a state of containment or a restriction of progression. A lockdown is an emergency protocol to prevent people or information escaping, which usually can only be ordered by someone in Authority|command . Lockdowns are also used to protect people inside a facility or, for example, a computing system, from a dangerous external event.
There may be various levels of lockdown. For example, in the case of buildings, a partial lockdown means that the doors leading outside of the building are locked and people may not exit or enter the building. A full lockdown means that people must stay where they are and may not exit or enter a classroom, apartment unit, store unit, an office space, condo unit or the building. If people are in a hallway they must go into the nearest classroom, apartment unit, condo unit, office space or store unit.
In its most common usage in corrections units, the term lockdown can be defined as a course of action to control the movement of inmates. Confining all prisoners, except workers, to their cells until the end of the day is a good example of a "lockdown period" in a corrections schedule. However a "full lockdown" is used when all prisoners are locked in their cells to prevent a riot or unrest fromm spreading or during an emergency.
In the United States , schools practice lockdowns in the wake of the Columbine High School massacre , when potential assailants possessing firearms (with a hostile intent) enter the school, or from internal events. It is considered an overreaction to lock down a school due to nearby criminal activity, such as a bank robbery, as criminals of that sort do not fit the profile of those who would take advantage of the perceived safety of a school (which, in reality, is a terrible place for refuge, as it is full of people in every room, all the time) and only rarely have such criminals entered a school while fleeing police.citation needed|date=May 2012 In some schools (unlisted for certain reasonscitation needed|date=May 2012, a "non-aggressive" lockdown would mean that all students would follow school lockdown procedure, and a student locker drug search would be performed by either the school staff, a K9 (canine) unit, the local police, or all three. However, not every school practices this, and some will actively search all lockers without requiring a complete lockdown.citation needed|date=May 2012 In American protest movements dating from the 1960s and 70s, the term lockdown applies to a person's attaching themself to a building, object, fence or other immobile object. This was originally done with chains and handcuffs, but other devices have been introduced, including tripods and tubes or pipes with handholds built in to link a person to an object or to create chains of people.Cite web | last = Young | first = Patrick | authorlink = | title = The Next Page: Hot trends in protest technology | work = Post-Gazette.com | publisher = PG Publishing Co., Inc. | date = 2007-03-18 | url = http://www.post-gazette.com/pg/07077/770421-109.stm | format = | doi = | accessdate = 2011-02-06
Examples
In the wake of the September 11 attacks (2001), a three-day lockdown of American airspace was initiated to prevent any remaining perpetrators from escaping.
In December 2005, the New South Wales Police Service initiated a lockdown of the Sutherland Shire and other beach areas of New South Wales to contain race rioting (and retaliative strikes). The New South Wales Labor government, in an emergency sitting of parliament, passed an array of amendments to legislation giving the New South Wales Police Service additional powers to 'lock down' targeted areas and roads within New South Wales. The legislation introduced to deal with the 2005 Cronulla riots was the Law Enforcement Legislation Amendment (Public Safety) Act 2005 (NSW). The Law Enforcement Legislation Amendment (Public Safety) Act 2005 (NSW) amended four separate pieces of legislation:
Crimes Act 1900 (NSW)
Bail Act 1978 (NSW)
Criminal Procedure Act 1986 (NSW)
Law Enforcement (Powers and Responsibilities) Act 2002 (NSW)
Under their new powers, the New South Wales Police Service locked down targeted areas and roads at Cronulla, Bondi, Coogee, Maroubra and Brighton-le-Sands to prevent persons of Middle Eastern appearance from committing reprisal attacks and prevent white supremacist agitatorsfrom further violence.
An example of a campus/school lockdown was demonstrated at the University of British Columbia (UBC) on January 30, 2008, when an unknown threat was made and the Royal Canadian Mounted Police (RCMP) issued a lockdown on one of the buildings on campus for six hours, cordoning off the area, and a campus alert was sent via email to everyone affiliated with UBC while students and faculties were to remain locked in the building. http://www.straight.com/article-131020/cause-for-ubc-lockdown-still-uncertain-but-initial-posting-may-reveal-some-clues Cause for UBC Lockdown still uncertain but initial posting may reveal some clues http://www.cbc.ca/canada/british-columbia/story/2008/01/30/bc-ubc-lockdown.html? ref=rss "Police increase presence at UBC following lockdown" http://www.theglobeandmail.com/servlet/story/RTGAM.20080131.wubclockdown0131/BNStory/National/home "Threat prompts lockdown at UBC"
On April 10, 2008, two Canadian secondary school s were locked down due to suspected firearm threats. George S. Henry Academy was locked down in Toronto , Ontario at approximately 2:00p.m. http://www.insidetoronto.ca/News/NorthYork/article/45610 "NORTH YORK: Two charged after George S. Henry Academy lockdown". The Emergency Task Force (TPS) were contacted and the lockdown lasted for more than two hours. New Westminster Secondary School was locked down in New Westminster , British Columbia at approximately 1:40 p.m. http://www.canada.com/theprovince/news/story.html? id=31b5f3d2-7491-4e18-8766-0c4f974ee44d& k=18879 "Teen arrested in connection with school lockdown". The Emergency Response Team (ERT) were called and the school was under lockdown until 4:30 p.m. Due to the size of the school, some students were not able to leave until 7:00 p.m.
Another example of a lockdown would be an Air raid|air raid emergency. During the 1940's and 1950's, neighborhoods such as Detroit, MI would practice a Blackout (wartime)|blackout . During this time, the city's Civil Defense workers would immediately activate the neighborhood air raid siren, and families would be required to do the following in order: 1. Shut off all appliances, such as stoves, ovens, furnaces; 2. Shut off valves for water and natural gas or propane, as well as disconnect electricity; 3. Close Blackout (fabric)|blackout curtains (plain black curtains that would block light from coming in or going out). Unlike an atomic bomb, where white curtains are used to reflect the blast, black curtains were used to prevent any airborne enemies from seeing in windows; 4. Get to a public shelter, a bomb or fallout shelter, or the household basement, and stay there until the local police dismissed the blackout. Although no longer practiced, air raid drills are still used by a small portion of people who would protect against any enemies. These blackout incidents would begin at 3:00 PM and usually end around 3:30 PM.citation needed|date=May 2012
