Haddad refused to comment on the report and said an investigation into the incident is still ongoing.
"I'm not going to engage in opinions on the use of force," Haddad said when asked if agents fired too many times. "Whether it clears them, whether they're prosecuted, it'll be up to the next level."
Haddad said it would take several more weeks before detectives finish their work and share their findings with the Michigan attorney general's office.
Attorney General Mike Cox will decided whether to clear the agents or charge them in connection with the shooting.
