Johnny has an adjoining locker with stickers from bands that advocate rock 'n roll, as well as marijuana use. Mr. Ackerman walked up to Fred and told him to open his locker for an inspection. When Fred grudgingly complied after demanding to see a search warrant, Mr. Ackerman looked into the paper bag and found small plastic bags containing marijuana, which is illegal to possess in this jurisdiction.

Mr. Ackerman seized the phone, the purse, the marijuana, fireworks and told Fred, Johnny and Jane to wait in his office while he called the police.Was Mr. Ackerman's review of Jane's texts lawful?
