More information wanted
But both men said they can't see the need for the long lockdown based on the information released so far by district and police officials.
Pochowski said most of the extended lockdowns he has heard of are because of unresolved issues involving gangs or other rivalries.
Capt. Brian Jennings, commander of Oklahoma City Police Department's school resource unit, said earlier this week police don't think Monday's incident was gang-related.
District spokeswoman Tierney Cook has said Superintendent Karl Springer wants the more stringent procedures in place until further notice to show the district's commitment to keeping students safe.
Blauvelt said students need to know more than that.
"I think the schools have got to be clear with kids why we're still in this lockdown, because I think for students not to understand why we are doing this, then they become very suspicious and then it becomes a game.
"If they don't believe this is a serious event, then they're going to take it as a game and they'll find ways to defeat it. ... I think you're due an explanation.”
