Newly released images show the weapons federal authorities say a 21-year-old Pennsylvania man was stockpiling as he allegedly prepared for an ISIS-inspired mass shooting. Jonathan Kramer was arrested near Pittsburgh after investigators say he purchased a semi-automatic rifle and nearly 200 rounds of ammunition. Agents also seized knives, a scope and other items. Federal authorities allege Kramer pledged allegiance to ISIS and discussed attacks involving firearms, explosives, drones and ricin, describing his plans as a mission to wage war on non-Muslims. The FBI says agents moved in before he could carry out the alleged attack. @​EricShawnTV ▻
