A more thorough explanation:

A prisoner of conscience is a person who has been imprisoned because of their political, religious, or other beliefs that they hold deeply. They have not used or advocated for violence. They may also be imprisoned because of their ethnicity, sex, color, or language.

An example of a prisoner of conscience is a person who is jailed for speaking out against their government's policies or for practicing their religion. They have not committed any violent acts, but they are imprisoned because of their beliefs.

Another example is a person who is imprisoned because of their ethnicity or language. They may be targeted by the government or other groups because of their background, even though they have not done anything wrong.

These examples illustrate how a person can be imprisoned simply for holding beliefs or characteristics that are different from those in power. It is a violation of human rights to imprison someone for their beliefs or background, especially if they have not committed any violent acts.
