We hold that the examination permitted by Penal Code section 171e and section 12031, subdivision (c) is constitutional and does not violate the Fourth Amendment. In the first place, the examination of the weapon [11 Cal.App.3d 792]
may hardly be deemed to be a search at all. The chamber of a gun is not the proper or usual receptacle for anything but a bullet or a shell. The loading of a gun simply affects the condition of the weapon by making it immediately useful for firing. The ammunition becomes, as it were, part of the gun. There is nothing private or special or secret about a bullet. The use of the word "examine" in the statutes instead of the word "search" is not at all a devious one. In examining the weapon, the officers are not attempting to find some kind of contraband which is unrelated to the gun itself.
But if the examination may be called a search, it is not an unreasonable one; and only unreasonable searches are forbidden by the Fourth Amendment. (Terry v. Ohio, 392 U.S. 1 [20 L.Ed.2d 889, 88 S.Ct. 1868].) It is, as we have said, limited to a single purpose. It does not have about it any except the slightest element of embarrassment or annoyance, elements overbalanced by far by the purpose of preventing violence or threats of violence. The minimal intrusion does not begin to approach the indignity of the frisk, as graphically described in Terry v. Ohio, supra, at p. 17, fn. 13 [20 L.Ed.2d at p. 903]. It is true that the frisk, as sustained in the Terry case, requires as justification something different than mere possession of a firearm in a proscribed place, but it requires a good deal less than cause for arrest.
What is "probable" in the case of a weapon must be tested by different standards from those which apply to other objects. When a gun is pointed at a bank teller, he might indeed reason to himself that it is just as probable that the gun is unloaded as that it is loaded, and that unless there were some particular indication to the contrary, he might act with assurance in refusing the demands of the person exhibiting the gun. But the nature of weapons is such that one does not measure probabilities by the standards that apply to other objects. It is true, of course, that in this case there was no such threat as exists in the case of the bank teller, but on the other hand, the carrying of weapons, particularly if it were done in large numbers on a college campus or in the other places mentioned by the statutes, would produce a show of force even though the weapons, or some of them, were unloaded.
Bearing in mind that a state is free, as Chief Justice Warren put it, "to develop its own law of search and seizure to meet the needs of local law enforcement," provided, of course, that the Fourth Amendment standard of reasonableness be not offended (Sibron v. New York, 392 U.S. 40, 60-61 [20 L.Ed.2d 917, 933-934, 88 S.Ct. 1889]), we hold that the mere examination of a weapon which is brought into a place where it is [11 Cal.App.3d 793]
forbidden to have a loaded weapon, is not unreasonable and that the statutes authorizing such examination are constitutional.
 In the brief filed by amicus curiae. American Civil Liberties Union, it is stated that the Legislature can, if it wishes, prohibit the carrying of firearms on campus, but cannot permit unloaded firearms to be so carried, modifying the permission with a power to inspect the weapons. It is argued that the legislative purpose is discriminatory because the wish of the Legislature is to give the police power to inspect firearms of persons whom they regard as suspicious and those whom they disfavor. Of course, legislation which is passed "with an evil eye and an unequal hand" (Yick Wo v. Hopkins, 118 U.S. 356, 373 [30 L.Ed. 220, 227, 6 S.Ct. 1064]), the legislative purpose being discriminatory enforcement, must be struck down. But there is not a shred of evidence in the record before us that the statutes in question have been enforced unequally. fn. 1
The exceedingly limited inspection
permitted by the statutes in question, applied only to persons who do choose to carry firearms where loaded firearms are forbidden, comes well within the orbit of reasonable inspection or search.
