A riot policeman watches as a police vehicle burns in Braamfontein, Johannesburg, South Africa, Tuesday, October 25, 2016. Rioters in South Africa set a police vehicle on fire Tuesday and stoned vehicles near a Johannesburg university that has been the scene of sometimes violent protests by students demanding free education. The violence broke out in streets near the University of the Witwatersrand at around the same time that student protesters met and marched off the campus, South African media reported.

A group of prospective police recruits, ready to be enrolled in the M23 controlled force, salute in the courtyard of a police station in Goma on February 6, 2025. More than a week after the battle for the North Kivu provincial capital, the M23 on Wednesday appointed people to public positions. Goma now has two officials for many public posts – two mayors, two governors – which locals said has created confusion. The M23 administration is still in its embryonic stages and struggling to respond to daily problems in the war-wounded city. (Photo by Michel Lunanga/AFP Photo)

Germany is on high-alert following the November Paris terror attacks and a credible threat at the Germany vs. Holland football match in Hanover. (Photo by Sean Gallup/Getty Images)

Serbian police officers of the Special Anti-Terrorist Unit pose for a picture in their base outside Belgrade October 8, 2014. When the killing of an unarmed black teenager by a white policeman in Ferguson, Missouri, in August sparked sometimes violent protests, the response of police in camouflage gear and armoured vehicles wielding stun grenades and assault rifles seemed more like a combat operation than a public order measure. Some U.S. police departments have recently acquired U.S. military-surplus hardware from wars abroad, but there are many law enforcers around the world whose rules of engagement also allow the use of lethal force with relatively few restrictions. But for every regulation that gives police wide scope to use firearms, there is another code that sharply limits their use. In Serbia, police may use measures ranging from batons to special vehicles, water cannon and tear gas on groups of people who have gathered illegally and are behaving in a way that is violent or could cause violence, but they may use firearms only when life is endangered.
