<p>It would be irresponsible not to clear the buildings in case an actual threat exists, even if it happens just once. I would be more scared for my son if they didn’t clear everytime because this nutjob could get frustrated if they didn’t clear them and do something potentially much worse. I’m also guesisng that law enforcement is advising them to continue as is, perhaps as part of an identification and capture strategy. In the end, they’ll catch this perp,send him/her to prison hopefully forever, and the kids will see this as character building and bonding.</p>
