It depends.
Usually, in a public place, anything is public property and you're free to film it. This is the reason why CCTV is allowed.
However, there are some situations which you will not be allowed to film. For example, secret operations by intelligence agencies. Capturing these on film will result in an extremely heavy fine and confiscation of electronic equipment such as cameras and computers - under the Official Secrets Act (or an equivalent law depending on country).
It is also a persons right that they are not filmed when requested. So, if a public servant tells you to stop filming, you must obey.
Yes, you have a constitutional right to film Police Officers in places where the public has the right to be. Some states have evesdropping laws, which the Police have been known to charge people with who record them. This is not only a false arrest but it's a gross miscarrage of justice as the Supreme Court has already ruled on this matter. Police and Municipalities that blatantly violate established rules of law can be subject to both prosecution and civil liability (Juries are not very friendly when their time is wasted or Police act inappropriately).
they can but they shouldn't
Police officers are public servants and as such, their images are part of the public record - EXCEPT- for pictures of confidential and undercover operatives. If you are somehow in possession of these types of pictures, and disseminate them, you would be liable, at the very least, for charges of criminal Reckless Endangerment.
All police officers are "public safety officers," as public safety generally includes law enforcement, the fire service, and emergency medical services. Some cities and counties have "public safety departments," where officers are cross-trained both as law enforcement officers and as firefighters. Officers perform police duties when not actually engaged in fire service duties.
Protection of the public and to enforce the laws of their jurisdiction.
Police want to know if you have a police record. Then they can look it up and see if you have a pattern of problems they need to be aware of.
According to the web site for the public safety department in Grovetown, their director is Al Robinson. Grovetown has a public safety department instead of separate police and fire departments. The public safety officers who work there serve as both police officers and firefighters. Grovetown doesn't have a "chief of police," but rather a public safety director.
Police officers are employees of your local state and federal government. Their salaries are a public record and are set commensurate with the prevailing wages of othere law enforcement agencies in their area and the prevailing salary scales predominating in that part of the country. You should research the agency you are interested in - all such things as working conditions, salaries, and duties are a matter of public record and most can be found on-line or by going to your local police agency and requesting a recruitment brochure.
I don't - police depend on the help from the public in most cases.
