US news media outlets are already preparing draft descriptions of future mass murderers based on previous descriptions of all former mass killers.
"I can't believe it, they were such a normal family" has already been earmarked as one potential leader, which has been quoted 43 times previously by friends and neighbors of killers such as the Colombine High School killers and John Lennon murderer, Mark Chapman.
Other comments, which are bound to be made are:
"I am shocked - he/she was so quiet"
"I would never have dreamed he/she would do such a thing"
"He/she never ever displayed any sort of psychotic tendencies"
"He/she was such a polite man/woman/boy/girl....I used to see him/her walking his dog"
"He/she never showed any interest in weapons. This is so out of character"
As America once again shakes it's head and asks why, and vigils are held for dead innocent children, gun sales rocket, NRA supporting Fox News exploits grieving families and the Hunger Games remains this years biggest selling DVD.
