New York State double-jeopardy laws would make it difficult to prosecute a suspect who had been found not guilty at a federal trial. U.S. Attorney Denise E. O'Donnell declined to (discuss) what federal charges were being pursued, but she said that in a case like this, potential charges would be abortion-related violence, the use of a firearm in an act of violence, crossing state lines to commit a crime, and, if the suspect's act was tied to an organization, violation of the so-called RICO statutes, which prohibit an organized criminal enterprise.
