However, he said the district has the right to ask individuals to leave the school if they disrupt the academic process.
"If we see a weapon, we go into lockdown," Tenbusch said, noting that the district was not placed on lockdown Wednesday because the incident happened as students were being dismissed.
He said lockdowns, as well as concerns raised by students, parents and staff during Wednesday's incident, cause a disruption in the school and justify the district's demand that those with weapons leave.
