His father is justifiably enraged at the US Govt. Ms Ortiz and Steve Heymann are certainly the primary culprits here - However MIT is equally if not more responsible for this mess that ended in a horrible and needless tragedy.
MIT has a higher duty than the Govt. It is in their charter to foster open access - and not only did they NOT stand up for Aaron, they actually made the prosecution malicious by refusing to ask for anything less than JAIL TIME http://gothamist.com/2013/01/15/aaron_swartzs_lawyer_mit_ref...
So MIT as good as killed Aaron along with the Govt.. for shame!
