A news cameraman in a public street was told by Mexican soldiers that he could not record an accident involving one of their trucks. He was told he could be there but not record the accident.
Here in the U.S. if you can be there, then you can record. In the surface, it looks bad, especially since it involves one of their vehicles, it gives the impression of a cover up at minimum.
This continues to be problematic, authorities having the right to protect a scene and reporters trying to do their job, if it's legitimate on both sides, there should be a middle ground of compromise.
