Discursive transgressions and security culture. Political-moral panics in the Spanish public sphere. In recent years, there have been various controversies in the Spanish public sphere based on humorous or critical messages that questioned the sacredness of certain identity and national symbols. Among others, the controversies generated by the writer Guillermo Zapata, the tweeter Cassandra Vera and the rapper Valtònyc can be cited. Following the analytical framework of moral panics developed by Stanley Cohen in the 1970s, and later updated, we analyze the media construction of these "popular demons", as well as the positioning of the different actors involved. To do this, we identify three moments in the construction of these panics: cultivation, operation and dissipation. And we observe its mutation over time, from a beginning where it is difficult to differentiate between moral panic and political scandal to a stage of maturity in which both phenomena can be clearly distinguished. Our approach is that these moral panics are a distinctive element within the political controversies generated in the public sphere, which also reflect a specific security culture in Spain, especially after the approval of the Citizen Security Law and the reform of the Code Criminal in 2015.
