A British man named Niyak was arrested by the Metropolitan Police for holding a sign stating 'Hamas is Terrorist' during a pro-Palestine march in London. The UK government designates Hamas as a terrorist group, yet the police deemed the sign a 'breach of the peace.' The incident, which also involved the display of a Union Flag, has sparked controversy, with critics arguing that the police should instead focus on those who become aggressive at anti-Hamas signs. The arrest has raised questions about freedom of speech and the enforcement of laws against a proscribed terrorist organization.
