BBC Silent Witness

I have always enjoyed Silent Witness but in the latest program the team of scientists were in Afghanistan and in a particular BBC manner they managed to put the Taliban as the hero's and the Brits etc made to be villains to the extent a White  British Soldier was portrayed as Taliban convert who was a suicide bomber. Apart from the act the program was not factualy correct, should a British Broadcasting company funded by the UK tax payer be supporting an enemy to our troops?  You listened to any BBC political program they always have a left wing slant. So why should we the tax payer fund it?
