On Criminal Minds
Note: While workplace shootings were never prominently featured on Criminal Minds, the pathology remains as a notable term of mention, or there have been some attempts demonstrated in the show.
 * Norman Hill ("Normal") - After hallucinating his boss and coworkers laughing and mocking him, he reached for a sawed-off shotgun that he currently had in his possession, intending to use it on them, but then relented after his boss gave Norman his condolences over the loss of his daughter.
 * Luke Dolan ("Dorado Falls") - In the wake of Dolan's massacre at an office, which left eight people dead, the BAU initially assumed that this was a standard example of workplace violence, even suspecting an employee who was absent at the time of the massacre.
