opinion: Per Curiam.
  Petitioner John Thomas Flower, a regional “Peace Education Secretary” of the American Friends Service Committee and a civilian, was arrested by military police while quietly distributing leaflets on New Braunfels Avenue at a point within the limits of Fort Sam Houston, San Antonio, Texas. In an ensuing prosecution before the United States District Court for the Western. District of Texas on charges of violating 18 U. S. C. § 1382 (“Whoever reenters or is found [within a military post] after having been removed therefrom or ordered not to reenter by any officer or person in command or charge thereof — Shall be fined not more than $500 or imprisoned not. more than six months, or both”), it was established that petitioner had previously been barred from the post by ordfer of the deputy commanda’ because of alleged participation in an attempt to distribute “unauthorized” leaflets. The District Court found that § 1382 “is a valid law” and was validly applied. It sentenced petitioner to six months in prison. A divided panel of the Court of Appeals for the Fifth Circuit affirmed.. 452 F. 2d 80 (CA5 1972).
  We reverse. Whatever power the authorities may have to restrict general access to a military facility, see Cafeteria & Restaurant Workers v. McElroy, 367 U. S. 886 (1961), here the fort commander chose not to exclude the public from the street where petitioner was arrested. As Judge Simpson, dissenting/noted below:
  “There is -no sentry post or guard at either entrance or anywhere along the route. Traffic flows through the post on this and other streets 24 hours a day. A traffic count conducted on New Braunfels Avenue on January 22, 1968, by the Director of Transportation of the city of San Antonio, shows a daily (24-hour) vehicular count of 15,110 south of Grayson Street (the place where the street enters the post boundary) and 17,740 vehicles daily north of that point. The street is an important traffic artery used freely by buses, taxi cabs and other public transportation facilities as well as by private vehicles, and its sidewalks are used extensively at all hours . of the day by civilians as well as by military personnel. Fort Sam Houston was an open post; the street, New Braunfels Avenue, was a completely open street.” 452 F. 2d, at 90.
  Under such circumstances the military has abandoned ' any claim that it has special interests in who walks, talks, or distributes leaflets on the avenue. The base commandant can no more order petitioner off this public street because he was distributing leaflets than could the city police order any leafleteer off any public street. Cf. Lovell v. City of Griffin, 303 U. S. 444 (1938), Schneider v. State, 308 U. S. 147 (1939). “[S]treets are natural and proper places for the dissemination of information and opinion,” 308 U. S., at 163. “[0]ne who is rightfully on a street which the state has left open to the public carries with him there as elsewhere the constitutional right to express his views in an orderly fashion.” Jamison v. Texas, 318 U. S. 413, 416 (1943).
  The First Amendment protects petitioner from the application of § 1382 under conditions like those of this case. Accordingly, without need to set the matter for further argument, we grant the petition for a writ of certiorari 'and reverse the conviction.
  Reversed and remanded.
  Mr. Justice Blackmun dissents, for he would grant the petition for 'certiorari and hear argument on the merits.
instruction: What follows is an opinion from the Supreme Court of the United States. Your task is to determine the ideological "direction" of the decision ("liberal", "conservative", or "unspecifiable"). Use "unspecifiable" if the issue does not lend itself to a liberal or conservative description (e.g., a boundary dispute between two states, real property, wills and estates), or because no convention exists as to which is the liberal side and which is the conservative side (e.g., the legislative veto). Specification of the ideological direction comports with conventional usage. In the context of issues pertaining to criminal procedure, civil rights, First Amendment, due process, privacy, and attorneys, consider liberal to be pro-person accused or convicted of crime, or denied a jury trial, pro-civil liberties or civil rights claimant, especially those exercising less protected civil rights (e.g., homosexuality), pro-child or juvenile, pro-indigent pro-Indian, pro-affirmative action, pro-neutrality in establishment clause cases, pro-female in abortion, pro-underdog, anti-slavery, incorporation of foreign territories anti-government in the context of due process, except for takings clause cases where a pro-government, anti-owner vote is considered liberal except in criminal forfeiture cases or those where the taking is pro-business violation of due process by exercising jurisdiction over nonresident, pro-attorney or governmental official in non-liability cases, pro-accountability and/or anti-corruption in campaign spending pro-privacy vis-a-vis the 1st Amendment where the privacy invaded is that of mental incompetents, pro-disclosure in Freedom of Information Act issues except for employment and student records. In the context of issues pertaining to unions and economic activity, consider liberal to be pro-union except in union antitrust where liberal = pro-competition, pro-government, anti-business anti-employer, pro-competition, pro-injured person, pro-indigent, pro-small business vis-a-vis large business pro-state/anti-business in state tax cases, pro-debtor, pro-bankrupt, pro-Indian, pro-environmental protection, pro-economic underdog pro-consumer, pro-accountability in governmental corruption, pro-original grantee, purchaser, or occupant in state and territorial land claims anti-union member or employee vis-a-vis union, anti-union in union antitrust, anti-union in union or closed shop, pro-trial in arbitration. In the context of issues pertaining to judicial power, consider liberal to be pro-exercise of judicial power, pro-judicial "activism", pro-judicial review of administrative action. In the context of issues pertaining to federalism, consider liberal to be pro-federal power, pro-executive power in executive/congressional disputes, anti-state. In the context of issues pertaining to federal taxation, consider liberal to be pro-United States and conservative pro-taxpayer. In miscellaneous, consider conservative the incorporation of foreign territories and executive authority vis-a-vis congress or the states or judcial authority vis-a-vis state or federal legislative authority, and consider liberal legislative veto. In interstate relations and private law issues, consider unspecifiable in all cases.
