Well, first of all, sniper rifles most likely don't have very high rates of fire. Second, they probably would have pretty high flash, so snipers may be easy to spot, if they don't move often. And third, from what i read, enforcers have such heavy armor, and wear helmets, and have such heavy weapons, then if they spot you, your basically vaporized, smashed, and utterly destroyed.
