From the Lafayette City Manager:
Earlier today, Acalanes High School went on total lockdown after a student texted a threatening message. After an all-out response from the Lafayette Police Department and Acalanes faculty and administration, the student was arrested, taken into custody, and it is likely that s/he will be prosecuted for the action. There are lots of things wrong about this, but among the most regretful is that the high school seniors were scheduled to have their senior picnic at 10:30A, and this stupid act disrupted their celebration. Anyway, everybody’s breathing easier now, and the police and school personnel can chalk it up as a very realistic drill. All involved commented that the twice-annual active-shooter drills paid off big time. Whew.
