And
@1J04 said it, the educator is a "Mandated Reporter", and they are required by law to report any child abuse and/or neglect. Every state has on the books laws requiring mandatory reporting of child maltreatment. Maryland has laws preventing allowing a minor access to a loaded firearm, and if an educator sees or hears that, they are required to report it to DHS/CPS. Failure to report is a criminal offense that can result in 3 years/$10,000 fine. Finally, a mandatory reporter acting in good faith is immune to repercussions.
Pretty much every state has similar laws on the books, even the most conservative ones.

On the lady letting the police in to search, she like the vast majority of law abiding folks out there took the easy way out and let them come in, see there were no violations, and leave to close out the report. Should she have told them to come back with a warrant? That's for none of us to decide, it was her life and her decision.
On the school official, they could have solved this whole mess with a quick "Let me talk to your parent" and gotten to the bottom of it in two minutes, versus go through all this mess. But let's face it, educators as a whole are amongst the staunchest lib industries out there along with health care, so for anyone to expect anything less than what happened in an urban area is pipe dreams. Don't give them a reason.
Moral of the story for all of us: Know your kids' teachers and schools, know your moves for before the police show up at your door in what you're personally willing to allow or fight, and for fuck's sakes don't give anyone an excuse to send the police/CPS to your door. That this happened in Baltimore metro, zero surprise in all of it there because if a teacher where I live had seen that, their first question would have been asking the kid if they're excited to get to hunt the next year, but in the city you get exactly what happened here.
