Burn it with fire

Instead of sending robots into dangerous situations, police should strap cameras onto these politicians and send them in to see if the danger is real. Robots are expensive and might be damaged if a barricaded criminal shoots them. Nobody ever misses a dead politician, so it would be no loss if they get whacked. Besides, his rotten replacement is waiting in the wings and won't cost anything till they get in office and start stealing everything they can get their greedy hands on.
