Protection against destruction by riots

The protection level against destruction by riots question in Securban concerns the measure types


 * Target hardening to ensure violence cannot overcome other measures taken (such as directing traffic flows or access control), can prevent a riot getting out of hand.
 * Directing traffic flows to reduce the chance for potential rioters to approach vulnerable areas or opponents.
 * Removing means by making sure any materials that might be helpful for riots are unavailable, e.g. by designing a road in asphalt instead of throwable bricks.
 * Controlling disinhibitors such as alcohol.
 * Access control can ensure only flows of the intended people enter or exit the area and can enforce and intended separation of crowds.
 * Screening can sometimes be applied (for examples at stadiums at high-risk matches) to ensure the nature of the visitors, such as scanning for a restraining order or for the presence of forbidden materials, such as fireworks or weapons.
