One such incident happened today. Many people on social media portrayed that Mexican tall ship as politically motivated, even loaded with migrants, intent on making a political statement.
The evidence, however, is that ship is actually a Mexican naval vessel used as a training vessel as it sails about the world on good will missions. It hitting the bridge was almost certainly an unfortunate and, for those injured or killed, tragic accident. The conspiracy theory was entirely unfounded and in error.
I'm seeing much fewer of those politically motivated but almost certainly erroneous posts on social media now, but very very few acknowledgments that the information previously posted was in error.
