While these aren't state specific they do apply in most cases. Maybe it will help clear up some confusion.

The only fact that saves the officer's stop of DeBerry, in my opinion, is the fact that it is unlawful in Illinois to carry a concealed weapon.
The tipster informed the police that DeBerry was armed, and it appears from the facts before us that the weapon was not in plain view.
I do not agree that this case would necessarily come out the same way if Illinois law, like the law of many states, authorized the carrying of concealed weapons.
At that point, the entire content of the anonymous tip would be a physical description of the individual, his location, and an allegation that he was carrying something lawful (a cellular telephone? a beeper? a firearm?).
This kind of nonincriminatory allegation, in my view, would not be enough to justify the kind of investigatory stop that took place here.
This section authorizes officers to demand identification only when a person is suspected of committing a crime, but does not govern the lawfulness of requests for identification in other circumstances. State v. Griffith, 2000 WI 72, 236 Wis. 2d 48, 613 N.W.2d 72, 98-0931.

52 F.3d 194 UNITED STATES of America, Plaintiff-Appellee, v. Coye Denise GREEN, Defendant-Appellant. No. 94-1675. United States Court of App
Regalado v. State, 25 So. 3d 600 - Fla: Dist. Court of Appeals, 4th Dist. 2009
"Despite the obvious potential danger to officers and the public by a person in possession of a concealed gun in a crowd, this is not illegal in Florida unless the person does not have a concealed weapons permit, a fact that an officer cannot glean by mere observation. Based upon our understanding of both Florida and United States Supreme Court precedent, stopping a person solely on the ground that the individual possesses a gun violates the Fourth Amendment."
In evaluating the validity of investigatory stops, we must consider the "totality of the circumstances--the whole picture." United States v. Sokolow, 490 U.S. 1, 8, 109 S.Ct. 1581, 1585, 104 L.Ed.2d 1 (1989) (quoting United States v. Cortez, 449 U.S. 411, 417, 101 S.Ct. 690, 695, 66 L.Ed.2d 621 (1981)).
Reasonable suspicion must derive from more than an "inchoate and unparticularized suspicion or 'hunch.' " Terry v. Ohio, 392 U.S. 1, 27, 88 S.Ct. 1868, 1883, 20 L.Ed.2d 889 (1968).
Moreover, "[c]onduct typical of a broad category of innocent people provides a weak basis for suspicion." United States v. Weaver, 966 F.2d 391, 394 (8th Cir.) (quoting United States v. Crawford, 891 F.2d 680, 681 (8th Cir.1989)), cert. denied, --- U.S. ----, 113 S.Ct. 829, 121 L.Ed.2d 699 (1992).
A number of the factors relied upon by Carrill can be characterized as "conduct typical of a broad category of innocent people." Weaver, 966 F.2d at 394. We reject the notion that Green's travelling alone, carrying a small bag, wearing new and baggy clothes, and failing to make eye contact with Carrill, are in any way indicative of criminal activity. Thus, these factors cannot play a role in assessing the validity of the investigatory stop.
Under Florida v. J.L., an anonymous tip giving rise to reasonable suspicion must bear indicia of reliability. That the tipster's anonymity is placed at risk indicates that the informant is genuinely concerned and not a fallacious prankster. Corroborated aspects of the tip also lend credibility; the corroborated actions of the suspect need be inherently criminal in and of themselves., 2001 WI 21, 241 Wis. 2d 631, 623 N.W.2d 106, 96-1821. State v. Williams
“Mr. St. John’s lawful possession of a loaded firearm in a crowded place could not, by itself, create a reasonable suspicion sufficient to justify an investigatory detention.” St. John v. McColley
The Tenth Circuit found that an investigatory detention initiated by an officer after he discovered that the defendant lawfully possessed a loaded firearm lacked sufficient basis because the firearm alone did not create a reasonable suspicion of criminal activity.
United States v. King (1993)
“The mere presence of firearms does not create exigent circumstances.” WI v. Kiekhefer (1997)
