Video From Inside Classroom on Lockdown During Michigan HS Shooting

There is a viral video going around that was recorded inside one of the classroom on lockdown during the fatal shooting at Oxford High School. There are conflicting reports on who is at the door telling students to come out. Students were suspicious after that person called them "bro." Which led to people online believing the voice of the shooter. The sheriff said that person was not the gunman and likely an officer trying to calm students.
