Re people afraid of saying the truth against the government in public ?

Its Argumentative essay, and Im with the side which says yes people feel afraid.

It should have more than five paragraphs.

explain in the paper why people feel afraid of saying the truth, also how to let people have the power and the courage to say the truth, and why governments threat the people and they do not want them to say anything true or real.

please you have to cover an important point which is bystander effect in separate paragraph.
