Why the Principal Can Search Your Purse | New Jersey v. T. L. O.

In 1980, a teacher at Piscataway High School caught two students smoking, leading to a search of TLO's purse by Assistant Vice Principal Choplick. The search revealed evidence of marijuana dealing, resulting in TLO's legal charges. Her lawyer argued the search violated the 4th Amendment, but the court initially allowed the evidence. TLO appealed, and the case reached the Supreme Court, which ruled that school officials could conduct searches with reasonable suspicion. The decision clarified the application of the 4th Amendment in schools, despite dissent from Justice Brennan.

How did Justice William Brennan view the search conducted by Mr. Choplick?
