It is settled by a long line of recent decisions of this Court that an ordinance which, like this one, makes the peaceful enjoyment of freedoms which the Constitution guarantees contingent upon the uncontrolled will of an official - as by requiring a permit or license which may be granted or withheld in the discretion of such official - is an unconstitutional censorship or prior restraint upon the enjoyment of those freedoms.

STAUB v. CITY OF BAXLEY, 355 U.S. 313 (1958)

Someone please explain how discretionary concealed-carry permits are at all constitutional given this?
