Excerpt:
Usaamah Rahim, who was fatally shot after waving a military knife at law enforcement officers in Boston, was originally plotting to behead Pamela Geller, an activist and conservative blogger, law enforcement sources told CNN on Wednesday.
But Rahim, a 26-year-old security guard who officials believe was radicalized by ISIS and other extremists, decided instead to target the "boys in blue," a reference to police, according to court documents.
"I can't wait that long," he said of the original beheading plan, according to an FBI affidavit filed in federal court in Boston.
