There seems to be no end to the number of side investigations that could be opened against these people. Was Dan White framed because he was somewhat of a whistleblower?
"Dan White was a former San Francisco police officer….he allegedly quit the force after reporting another officer for beating a handcuffed suspect."

"Dianne Feinstein, who was then President of the San Francisco Board of Supervisors, saw White immediately exit Mayor Moscone's office from a side door and called after him. White sharply responded with "I have something to do first."
White fled the scene as Feinstein entered the office where Milk lay dead. She felt Milk's neck for a pulse, her finger entering a bullet wound. Horrified, Feinstein was shaking so badly she required support from the police chief after identifying both bodies. Feinstein then announced the murders to a stunned public, stating: "As President of the Board of Supervisors, it's my duty to make this announcement. Both Mayor Moscone and Supervisor Harvey Milk have been shot and killed. The suspect is Supervisor Dan White."
White was convicted of the lesser crime of voluntary manslaughter. The verdict proved to be highly controversial, and many felt that the punishment so poorly matched the deed and circumstances that most San Franciscans believed White essentially got away with murder.
White was paroled in 1984 and committed suicide less than two years later.
The revolver used, serial number 1J7901,has gone missing from police evidence storage, possibly having been destroyed."
