without wishing to appear trite or contrary might I point to research by Baron and Ransberger, conducted into 102 riots in the United States of America in the four years between 1967 and 1971, that concluded the frequency of violence and ambient temperature are curvilinearly related, evidence strongly suggested that the conditional probability of a riot increases monotonically with temperature. Whilst not attempting to devalue the argument for proper care in the design of modern cities, which is, of course, fundamentally important in the nurturing of human society, I might draw attention to the dissipation of violent activity with the arrival of rain. I had experience ( as a press photographer ) of the Toxteth, Moss Side and Brixton unrest of the early '80's without exception conditions were perfect to be out late in the evening. This is not to downplay the terrible difficulties and constraints we face as a society, but is offered only as a rational, scientific, context in which to consider human behaviour. Sometimes conditions are just right for fighting. I also had the misfortune to be in Cairo for the fall of Mubarak this January, my experience of that unrest and the difficulties we endured in Hackney are quite different. Timothy Soar.

London.Given locational evidence that riots also tend to happen in areas with an Index of Multiple Deprivation above a certain level, and in areas lacking a coherent local identity - a strong sense of 'place' and 'belonging' - can this lead us to a Probability formula in the form of
P(R) = f (t) +f (p) + f (d) +f (pl)
Where R is Riot, t is temperature, p is precipitation, d is deprivation and pl is a sense of place?
And for 10 marks, which of the four factors is the easiest to alter?
