1. A pyrotechnic self-combustible riot control composition, comprising: a. O-Chlorobenzylidene malononitrile (CS) as riot control agent,b. fuel,c. oxidizer,d. polycarbonate as binder,e. magnesium carbonate hydroxide pentahydrate as stabilizer, andf. dye. 2. A pyrotechnic self-combustible riot control composition according to claim 1, characterised in that the fuel comprises at least one of sucrose or lactose. 3. A pyrotechnic self-combustible riot control composition according to claim 1, characterised in that the oxidizer is potassium chlorate. 4. A pyrotechnic self-combustible riot control composition according to claim 1, wherein the dye comprises one or more of 1,4 dihydroxy anthraquinone, 1-(p-tolylamino)-4-hydroxy anthraquinone, 1-methylamino anthraquinone, 4,4-methylidyne-bis-3-methyl-1-phenyl-2-pyrazolin-5-one or 9,10 anthraquinone. 5. A pyrotechnic self-combustible riot control composition according to claim 1, characterised in that the composition comprises: a. 20% to 30% wt CS,b. 25% to 30% wt sucrose or lactose,c. 25% to 30% wt potassium chlorate,d. 7% to 10% wt polycarbonate,e. 6% to 15% wt magnesium carbonate hydroxide pentahydrate, andf. 3% to 5% wt 9,10 anthraquinone, with the amounts for each component of the riot control composition selected within the listed range and combined to total no more than 100%. 6. A method for making pyrotechnic self-combustible riot control composition, comprising steps of: a. pre-grinding sucrose, potassium chlorate, magnesium carbonate hydroxide pentahydrate and 9,10-anthraquinone to a fine powder and passing the fine powder through a #120-140 mesh sieve,b. dissolving polycarbonate (PC) in tetrahydrofuran (THF) at 40±5° C.,c. after dissolution of the PC, adding O-Chlorobenzylidene malononitrile (CS) and other powdered ingredients to solution,d. maintaining the resultant solution at 40±5° C. for at least 3 hours during stirring and removing the solvent,e. removing the resultant solution from heat and allowing the resultant solution to dry into a dry mixture,f. adding the dry mixture to a ball mill and grinding the dry mixture into a second fine powder for 30 minutes, andg. compressing the second fine powder using a tablet pressing machine at a pressure of 7,000-8,000 pounds per square inch to achieve a tablet density of 1.2-1.4 g/cm3.
