I do not need figures and percentages to tell me what's going on. I can see this at roots level, as we all can. The Detective Sgt who I met with told me that the predominant ethnicity for crime in my part of London is Somali. He told me that the whole area had changed and that I should not be walking home from the tube station even in the early evening. Somalia is a lawless country, and Somalis do not recognise or care for authority, think women are stupid if they do not have a male protector and will always strike at the most vulnerable.
But for those who live by figures, here are some for you.
There has been a surge in the number of Muslim prisoners for non-terrorism crimes.
In 2002, 5,502 prisoners in England and Wales said they were Muslim, and by Dec 2014, it had reached 12,225.
The overall prison population has also increased, but that 20% increase in the jail population has been outstripped by the rise in Muslim inmates - up 122%.
The percentage rise in Muslim prisoner numbers has been far greater than the Muslim population increase: Muslim inmates now account for 14.4% of those behind bars, compared with 7.7 % in 2002.
A Ministry of Justice analysis in 2013 suggested that 30% of Muslim prisoners weren't British - last year the top 10 overseas nationalities included inmates from two predominantly Muslim countries, Pakistan and Somalia.
(Unfortunately tabulation is not recognised on MN).
