Well this is only meaningful to those who follow the business news closely enough to know what LIBOR is, but both shooters' Dads (Lanza, and Holmes from the Batman shooting) had been scheduled to testify in the LIBOR scandal case. (interest rate fixing on the parts of the big banks, skimming billions from economies into the banksters' pockets) Holmes' father worked for FICO, and Lanza's father is GE's tax director. Both men were to testify, the case is going on right now.
Pretty weird coincidence.
Also explains the size of the Lanzas' house.
