They have conditioned the populace to be sheeps for shekels. The enemy is not brave, therefor they do care about their live's, and work hard not to lose it; as they go after yours. Actually what they are doing is in their training. They are careful but they always work towards the direction of the kill, doubling down, and never ending until their magic works by persistence. They know most will not confront indefinitely due to "statistics" of which they want to make you one of.
