FBI discovered a DHS document describing improvised explosive devices during investigation of Trump’s would-be assassin

Among the documents Donald Trump’s would-be-assassin studied while formulating his plans for an attack on the former president was a public document from the Department of Homeland Security, describing different kinds of improvised explosive devices and the number of explosives needed to inflict casualties over certain distances, a senior law enforcement official told CNN.

The FBI discovered saved images of the fact sheet, titled “IED Attack: Improvised Explosive Devices,” in early searches of Thomas Matthew Crooks’ electronics. While the document from the National Academies and DHS also explains what to do in an IED attack to protect yourself and others, its focus is on the key properties and conditions for using destructive, explosive devices. The document, which is more than a decade old, remains online.

The FBI would not respond to CNN’s questions about what specifically was found on the shooter’s electronics, but the agency said that any questions regarding the DHS document should be directed to DHS.
A DHS official told CNN the department “provides information to the American public on how to protect against a range of potential homeland security threats.” The department, the official added, “cannot speak to the FBI’s investigation” nor “speculate about any documents that may have been found on his devices.”
