The Czech presidential couple attended a film screening at the Karlovy Vary International Film Festival, sparking criticism online. Social media users accused them of not standing during the Czech national anthem before the film began, with one post calling them disrespectful. However, the video circulating online has been revealed as deliberately manipulated. An investigation, part of a series called “Řetězak,” confirmed the video was altered. The controversy highlights the potential for misinformation and quick judgment on social media platforms. The authenticity of online content is now being questioned in relation to the incident. This manipulation aimed to falsely portray the presidential couple in a negative light.
