Generate text that refutes this claim: Free speech is not useful in this context, as riot is never legitimate in a free society  Riots should not be tolerated in a free society as there are already legal and peaceful methods of dissenting such as through demonstrations, petitions, and contacting your representative in Parliament. It demonstrates a fundamental unwillingness to engage with not only the apparatus of the state, but society more generally. Rioters have no regard for the public, and the violence and damage they cause harms everyone. Riots tend to do little to actually challenge the state, but rather they tend to harm the most disadvantaged, those who happen to be in the vicinity of the mobs. The freedom of speech social media provides to its users is being fundamentally misused in the context of riots. [1] When speech is used to organize violence, it must be curtailed for the sake of society as individuals security and safety is more important that freedom of speech that is briefly curtailed. Violence damages long after the event whereas those who have their freedom of speech curtailed for a few hours can swiftly voice their opinions once the riot has ended and the block lifted.

Of course we do not want freedom of speech to be misused to incite and organise rioting and violence but that does not mean that it is always illegitimate. Riots may sometimes be the natural outgrowth of bad policy and a government that has been unwilling to listen to peaceful forms of protest. Disenfranchised groups may be forced in extremity to turn to these sorts of activities and the state should take heed when they occur instead of seeking to wield its power over the internet and mobile phones to crush dissent. This is what happened in the revolutions in the Arab world. When a riot does have a substantive cause then it is essential that social media is accessible as it is the way for the rioters to get their side of the story across.
