Wire fencing might seem mundane, but it played an important role in how the US was settled and shaped. Department of Transportation SHARE This section is in list format but may read better as prose.

( December 2019) Police AdviceThe police advise against the use of such methods of intruder prevention due to the risk of legal action if someone is injured. Of course, it is not only intruders and trespassers who risk being injured by barbed wire or broken glass. Householders owe a much greater duty of care to anyone on the property with permission including guests and people who have implied permission, such as the postman. Consider the danger posed to any children who may be visiting the property. If a child was injured after climbing on a wall in which broken glass is embedded, the householder is very likely to have breached their duty of care.

It may seem that the best way to avoid being burgled is to make sure that burglars cannot get anywhere near the property - especially for people living in semi-detached and detached houses. Placing barbed wire, broken glass, nails or carpet gripper on the wall surrounding the property may seem like the ideal solution. This may not be inherently illegal but there are restrictions on what householders can do - careful consideration should be given to the legal position before any of these deterrent methods are used. More significantly, barbed wire was used extensively by all participating combatants in World War I to prevent movement, with deadly consequences. Barbed wire entanglements were placed in front of trenches to prevent direct charges on men below, increasingly leading to greater use of more advanced weapons such as high-powered machine guns and grenades. A feature of these entanglements was that the barbs were much closer together, often forming a continuous sequence. [30]

Temporary Fencing

Fencing consisting of flat and thin wire was first proposed in France, by Leonce Eugene Grassin-Baledans in 1860. His design consisted of bristling points, creating a fence that was painful to cross. In April 1865 Louis François Janin proposed a double wire with diamond-shaped metal barbs; Francois was granted a patent. Michael Kelly from New York had a similar idea, and proposed that the fencing should be used specifically for deterring animals. [8] van der Ree, Rodney (2016).

During the Soviet–Afghan War, the accommodation of Afghan refugees into Pakistan was controlled in Pakistan's largest province, Balochistan, under General Rahimuddin Khan, by making the refugees stay for controlled durations in barbed wire camps (see Controlling Soviet–Afghan war refugees).
