Remember, like others are pointing out, that they all rely on a constant flow of Treats. Right now they're so powerful because they have an endless supply of Treats, falling right off a taxpayer-funded conveyor belt into their gaping maws. Now imagine if American society caved in and the conveyor belt stopped. If you cut off their supply lines, if they can't get their clammy fingers on their guns, body armor, or hell, food as easily as they usually can in their cushy suburban lives, they'll quickly buckle. Its not just a question of strength - the source of the strength is also important to consider.

Edit: I should also point out that this applies equally to the police and military
