I want to know the answer to the following question:
How did some people describe Filiberto Ojeda Ríos's death?
All the background I'm provided with is that "In 2005, fugitive Puerto Rican Nationalist leader Filiberto Ojeda Ríos died in a gun battle with FBI agents in 2005 in what some charged was an assassination.[citation needed]". Is that enough to answer the question?
