A Black Lives Matter (BLM) “protest” group in Georgia modified fireworks and turned them into nail-laced bombs that they chucked at the Atlanta Field Office of U.S. Immigration and Customs Enforcement (ICE), a new document obtained by federal law enforcement officers reveals.

The commercial-grade fireworks-turned-bombs were discovered almost immediately after the “protest” ended last Sunday, prompting federal officials to investigate. What they found is that the makeshift devices were intentionally tweaked to make them deadly, putting the very lives of BLM targets at risk.
