The people investigating the Clinton email case should have their input respected when it comes to deciding whether or not to charge Secretary Clinton. The meeting that Lynch took with former President Bill Clinton made the process look extremely tainted, so going against the recommendations of law enforcement personnel would make the case look dirty -- and rightly so.
Loretta Lynch should accept the FBI's recommendation in the Clinton case so as not to cast doubt on her professionalism given that she met Clinton on the plain. Also, being a political appointee, she should just adopt the recommendation to avoid what others may passive as conflict of interest of political influence incase she rejects the recommendations.
Lynch should accept the FBI's recommendations. The FBI is at the top of its class so it only makes sense that people would listen to them about an investigation. It doesn't matter who investigates things because they are all working towards the same thing. The FBI's opinion should be accepted.
Loretta Lynch should except the FBI's recommendation in the Clinton email case, but only to the extent it is advisory in nature. Lynches job is not to go forward based on recommendations from investigative agencies. Her job is to take the lead and prosecute cases as required to buy her job and the law.
