He speaks to lawyers, journalists, and fellow artists like Jammer, Meridian Dan and Big Narstie to find out whether the prohibiting of grime music events by London police is a cause for concern, rather than a solution to crime in the English capital.You can watch Form 696: The Police vs Grime Music on Noisey from this Thursday.Follow the contributors on Twitter: @JMEBBK @jammerbbk @meridian_dan @djlogansama @bignarstie
