Following a year-long investigation into the December 14 shooting at Sandy Hook Elementary School in Newtown, Connecticut, the state’s Department of Emergency Services has released several gigabytes of information gathered by law enforcement officials, including on-scene video footage, photographs, and previously sealed police reports.

“The investigation of this incident is unparalleled in the one hundred and ten year history of the Connecticut State Police,” Commissioner Reuben Bradford writes in an introductory letter published today.

Plenty is redacted, however. Much of the video footage, for example, consists of a blue “CONTENT REDACTED” warning.
