<p>[Terry</a> v. Ohio](<a href=“http://www.law.cornell.edu/supct/html/historics/USSC_CR_0392_0001_ZS.html]Terry”>John W. TERRY, Petitioner, v. STATE OF OHIO. | Supreme Court | US Law | LII / Legal Information Institute)</p>
<p>Cops CAN stop you when walking if they feel something is suspicious. The only question is did the cop believe he had sufficient reason. Did the student stumble? Did it smell like alcohol? Did the student emerge from a location of a party? </p>
<p>Game over… </p>
<p>This is similar to sobriety checkpoints/tests which are also legal per SCOTUS.</p>
