Some William Aberhart High School students in northwest Calgary are upset the school's administration did not immediately share information about a possible shooting threat. Students Brittany Lockhart (left) and Asia Littleshields say the administration of William Aberhart should have informed students more quickly of a threat made by a fellow student. The administration is asking Aberhart students to stay vigilant and be aware of what is being written on their friends' blogs and social media posts. (CBC)According to the letter, signed by the principal Tamie Annis-Johnson, William Aberhart did take measures — including the hiring of a security guard and locking all exterior doors, except the main entrance. The student's threat to shoot a firearm at school before the end of June was discovered by an assistant principal during a review of an anonymous student survey.
