Projecting an image of legitimacy behooves the government because it makes everything they do (and there is almost always someone who loses dearly whenever the government does something) that much less likely to be resisted. Government is always pushing at the limits of its authority or at least going right up to them so just "seeming" a little more legitimate in the minds of as many people as possible pays back because at the margin that turns into a bunch of fights you don't have to fight, all the work you don't have to do to justify your actions, the appeals that aren't filed, etc, etc.
Think about how HN just takes whatever the EPA says at face value vs scrutinizing ICE. Every office, department, etc, etc, aspires to get the EPA treatment from as much of society as possible. Acting the part is part is part of that.
