Using opinions in governing

My topic is government officials should be allowed to express their own opinion. First of all, I think government officials should be able to express their own opinions. They should be able to because the best way to get them motivated to work well is to let them do what they feel is right. If they were forced to do something that they would not feel is right, they would have less motivation and thus creating a balance-less and corrupt government. For example, Stanley McChrystal lost his job when he said innappropriate things in an interview. However, if he had been doing a great job as general in afganistan, then he should not be fired because he stated his opinion. That is an example of why government officials should be able to express their own opinion.
