A democratic government allows its citizens to speak their minds: a true democracy values everyone's opinion. And it is by collecting different opinions that a government can develop its nation in favour of its citizens.
However, sometimes governments intervene to prevent citizens from voicing their opinions. For example, if citizens are spreading rumours that could lead to social unrest, then a government may forbid such rumours being made public. Although social unrest is dangerous, some governments can use such fears as an excuse to censor criticism against them.
Before the arrival of the internet, the tried and tested way to speak out was to organise a protest.
In many countries, crowd actions, such as protests and union strikes, are recognised as part of the freedom of speech and are protected by law. In Hong Kong, according to Article 27 of the Basic Law, residents should enjoy freedom of speech, including the right to protest and strike.
But, if they grow out of control and threaten public safety, governments have the power to call off such protests. This helps to protect innocent members of the public if protests become riots. Yet governments can use the concern of public safety as an excuse to repress reasonable protests.
Journalists also help to maintain and fight for democracy by reporting on events using the protection of freedom of speech. They can provide the public with information about actions by governments and big business.
