History
The Police Federation of England and Wales began lobbying for the introduction of riot shields following the 1976 Notting Hill Carnival
The Notting Hill Carnival is an annual Caribbean Carnival event that has taken place in London since 1966 riot, during which many officers were injured with thrown stones, bricks and bottles. At the time riot shields were already common in Northern Ireland and mainland Europe; British forces deployed them during the Cyprus Emergency

in the 1950s, French police used them during the May 1968 riots, and British forces had been using them in Northern Ireland since at least 1969. Riot shields were first used in England during the 1977 Battle of Lewisham. While the Metropolitan Police Service designed them to be a passive and defensive item only, ''New Scientist

'' reported "the production of the shields t Lewishamwas part of what can only be described as an extremely aggressive operation". Many protesters were deliberately struck with the shields. A police spokesperson stated that a police officer who feels threatened would strike with whatever he had in his hands, adding "I don't see how you can stop him using the riot shield to hit a person".[

Shields are typically either round or rectangular in shape, with lengths between and varying widths. Most riot shields, when utilised properly, will protect the user from the top of the head to the knees.[ Shields will typically be slightly cylindrical and have handles made out of either metal or reinforced plastic affixed to them with either glue or grommets.][ Handles will be designed so that the shield-bearer can hold onto them with a fist, and the shield will often feature additional protection at the point where the forearm rests against it, as well as Velcro-strapping to keep the forearm in place.][ A shield may have a storage compartment for a baton or non-lethal weapon, and some may be designed to be interlocking with a shield on either side, so as to form a more effective shield wall. The type of shield used will vary, depending on both the situation and objective of a mission and also department budgets.][
Concave shields have been designed for pinning down and hand-cuffing rioters or prisoners, and electric shields designed to deliver a non-lethal electric shock to the person the shield is in contact with also exist.][ These shields, which began being manufactured in the 1980s, feature metal strips on the outside of the polycarbonate. A shock is delivered through the strips via a button on the side held by the bearer. Electric shields have caused several deaths. In 2011, ]Raytheon

Use and effectiveness
Whether riot shields are used will depend on the commanding officer's choice of force in combating protesters. It is recommended that security forces equipped with riot shields also utilise non-lethal weapons, overwatch

, and reserve forces. The riot shield is designed primarily as a defensive weapon, though it can be used in an offensive manner when in direct contact with protesters. They are designed to be affixed to the non-dominant arm and held at a slightly inward angle to deflect thrown objects into the ground.[ When protesters come in direct contact with riot shields they will typically try and take hold of them. If protesters attempt to grab the top of a shield, security forces are instructed to strike at them with their free hand. If protesters attempt to grab the bottom of a shield, they are instructed to drop to one-knee and ram the shield into the ground with force, thereby pinning the protester's fingers or hands. Riot shields are frequently used in combination with batons.][
Riot shields have been shown to be an effective way of driving back protesters and preventing them from pushing through police lines. A National Union of Mineworkers official stated that while it had been very difficult to break through police lines in the 1972 UK miners' strike when police had no shields and were relying heavily on the wedge formation, it had become outright impossible by the 1984 strike as by then the police had abandoned the wedge and instead adopted the riot shield and baton combination. The official concluded that unarmed protesters stand no chance against police with riot shields.][ The riot shield and baton combination is considered strong enough to handle all but the most extreme riots. If this combination is not deemed sufficient police may escalate to using additional methods such as ]water cannon

Riot shields may be used in conjunction with non-lethal weapons such as CS gas in a method known as the "Tap-down technique". In this method, an officer with a projectile weapon will approach a shield-bearer from behind and tap on their shoulder. In response, the shield-bearer will drop to one knee while keeping the riot shield affixed in front. The officer with the projectile weapon will lean into the shield-bearer's back with their knee, extend the barrel of their weapon over the shield and fire. This method allows maximum protection to both the firer and the shield-bearer.][ "Extraction teams" also use shields to their advantage. An extraction team is generally made up of reserve forces, and serves to extract personnel in danger or capture individual protesters. The team can be deployed from any point behind a shield wall. On instruction two officers on the front line will take a step back and to the left and right respectively, allowing a temporary gap from which several officers will depart; the gap will be closed after the last officer has gone through. A target will be identified, and it will be the pre-assigned goal of one officer to control the target and another to cuff them. Additional officers will provide cover. Once the protester has been restrained the shield wall will temporarily open to allow the protester to be dragged through. It is recommended that extraction teams venture no further than 10 meters from the shield wall.][
While riot shields offer an effective form of protection in themselves, their use may encourage people to throw objects at the bearers.][ A ]chief superintendent

in the UK stated that while protesters were generally reluctant to assault police, that reluctance seemed to disappear if officers had riot shields. It has been observed that protesters may not throw objects until the police bring in shields, and some people will deliberately throw objects at the shields themselves, indicating that they do not actually want to injure the police.
