Mike Campbell with the concert date set for Tuesday, November 16. However, students soon learned that a clause in Regulation 1320.1 prohibiting assemblies by business-sponsored groups prevented plans for the concert from being carried out. On Monday, November 15, students began a Taking Back Tuesday movement advocating a schoolwide skip day on the day of the cancelled concert, but it dissolved after Campbell's schoolwide address that afternoon. Following the incident, students and parents appealed to the school board to return pep rallies to the instructional period and to reconsider the regulation.

There is no evidence that Cho singled either out during the attack or even knew them. Although Cho's motivation for the shooting is unknown, his suicide note mentioned vague references to his emotional turmoil. While a few students recall instances of Cho being teased and mocked at Westfield, most left him alone and were not aware of his anger. It is unknown if or how much his experience at Westfield contributed to his mental breakdown. Journalists from the international media arrived at Westfield the day Cho's identity was announced, prompting a ban on reporters at six athletic games due "the impact... on school children, academics and other
