Violent London Riots

Violence has broken out for a third consecutive day in London, with riot police deployed and firefighters tackling blazes across the capital. Shops were looted and buildings, among them a furniture store in Croydon, set alight as police clashed with youths. Trouble first flared on Saturday after a peaceful protest in Tottenham over the fatal shooting of a man by police.

The chart for Mars entering Cancer tells the story without resorting to any other methods. Mars tends to be at it's worst in Taurus, Libra, and Cancer- where it's considered fallen, as the red planet is exalted in Capricorn, the sign opposite Cancer.
