Schools and Public Relations

It is instructive that a public relations officer for a local school district has written the newspaper about how the schools just need more money to do their job. This is exactly the point of discussion. A public relations officer's job is supposed to be to favorably influence public opinion and behavior and is essentially a lobbyist for the company involved. This one is just doing her job. The but is why a public school district needs a public relations officer in the first place?
