How does the number of journalists compare to previous years? How does this compare with other years that featured similar amounts of public protesting and social unrest? How long were journalists kept in custody? The number of arrests is certainly concerning, but I think there is a lot to consider with 2020 and that statistic alone isn't enough for me to conclude we are sliding into an authoritarian police state. It's definitely something that should be investigated further, though.
