Not at all. Rather, an officer has a much easier time justifying a lawful detainment than a private citizen does and is on much more solid legal ground if he or she has to use force in the furtherance of a legal goal. Officers also typically have more training and experiencing both in preventing the need for such force and using it appropriately when necessary. (There are, of course, examples to the contrary.)
If an officer truly just unlawfully detains you, then the question becomes whether or not that unlawful detainment violated a clearly established constitutional right. If so, qualified immunity generally doesn't apply and someone is getting out their checkbook. In fact, as an agent of the state, an officer is at greater peril if they violate your rights as they can be both civilly and criminally liable at both the state and federal level and they can also receive departmental discipline. What that means is that a single action can result in repercussions for the officer in five different venues.
Again, I am not a lawyer and I am skipping over a lot of important details that aren't really relevant to a hypothetical like this.
