 SCP-001 is the projectile which killed US President John F. Kennedy, fired by an unidentifiable number of assailants acting simultaneously, as part of one or more conspiracies. Upon impact, human perception began falling out of sync with objective reality at an individual level. The events surrounding SCP-001's trajectory are designated as Incident 001 Gamma. Although the divergent standards of objectivity are largely compatible enough to allow for human society to function, that does not mean they are not a threat to the long-term viability of human civilization and intelligent life as a whole. It is possible that the current formation of reality exists as a result of a VK-class reality restructuring scenario.
