3. John Law, a local police officer, is sitting outside an AM/PM around Midnight.He is eating a protein bar and drinking an energy drink when he observed a man walking up to the entrance of the AM/PM.The man then walked away from the entrance and met up with another individual on a street corner while repeatedly walking up and down the same street. The men would periodically peer into the AM/PM window and then talk some more. The men also spoke to a third man whom they eventually followed up the street. The officer believed that the men were "casing" the store for a potential robbery. The officer decided to approach the men for questioning, and given the nature of the behavior the officer decided to perform a quick search of the men before questioning. A quick frisking of one of the men, Jake, produced a concealed weapon and Jake was charged with carrying a concealed weapon, a felony.

Jake, hires a lawyer and fights the charges against him.He believes that his greatest argument is that the officer did not have probably cause to search and seize the firearm.Do you agree or disagree?Within your answer, please discuss whether the search was lawful or unlawful.In other words, did the search violate Jake's 4thAmendment rights?
