“…The frequency of pre-incident behaviors in the general campus population remains uninvestigated (Gisburne, 2003;Meloy, Hoffmann, Roshdi, Glaz-Ocik, & Guldimann, 2014), which has related to assertions that pre-incident behaviors are common, not predictive of subsequent violence, and likely to subject non-dangerous students to unnecessary police attention (Gisburne, 2003;Goodwin, 2014). The impact of threat assessment procedures on general campus violence have not been explored, which corresponds with potentially unwarranted resource competitions between campus targeted violence, sexual assault (Paul & Gray, 2011), stalking (Buhi, Clayton, & Surrency, 2009), and general crime (Selwyn, 2008) prevention efforts. The reporting decisions of pre-incident observers have received limited review (Hollister, Scalora, Hoff, & Marquez, 2014b;Sulkowski, 2011), despite several campus attacks occurring partly due to bystanders failing to extend pre-incident concerns to authorities (Drysdale et al, 2010;Scalora et al, 2010).…”
