Goverment involvement with disease control

I dont think the Government shouldn't be that involved with the isolation of people with dangerous infectious diseases. My opinion is based on the movie the Outbreak where I saw how the government treated the people who might of had the deadly disease. For example, when some of the people from the small town tried to escape because they couldnt take the confusion anymore the army shot them down. Not only that they shot it right in front of a family of children. I think that was a little over the top. Another thing is when the the Government decided to make a black out or kill everyone in that small town. This decision was made without the towns peoples knowledge and also when there was a chance that there could be a cure that could help the people. Sometimes the government only cares about the security of the nation and not about the feelings of the people living in the nation. It isn't because the government is coldhearted its because sometimes when the whole world is at stake people panic and don't try to find another solution. They just take the first route out of the mess before they  think about the consequenses. However more times than not people react for their own needs. In the Outbreak the goverment were not thinking about the towns people they where thinking about protecting their secret of a weapon. So my opinion is that no the goverment shouldnt be involved in the process of isolating people they should hand that over to the people who know the facts and dangers of what is at stake. Those people would be the doctors and scientist who know about viruses and other biohazards through and through. I dont think the army had to be involved with isolation, i think the police officers might of been enough but if things get unbearble for the polices then the army can step in but if not then the army should stay out of the isolation process.
