All too often, mass events such as football matches or public demonstrations turn into pitched battles resulting in the destruction of street furniture and sometimes in personal injury. The demonstration may start out as legitimate and peaceful like those organised by anti-globalisation movements, but then things go wrong.
Les spectacles de masse, comme le football, les manifestations publiques - en principe légitimes et pacifiques, comme celles des mouvements antimondialisation - deviennent, à de trop nombreuses reprises, des manifestations violentes entraînant des destructions brutales du mobilier urbain voire des blessés.
