Another case where a reporter shows his credentials and gets arrested anyway. Attorney General acknowledges that the action was improper.

The second one does not seem like a major problem to me, as the police might not know a random filming guy showing some piece of paper to be an actual reporter, rather than just a friend of the rioters filming their action for YouTube. It seems it also was resolved.
Unless there's an easy way for police to make a credible determination if the media badge is valid, I would count it as an honest mistake with no major consequences.
Again, this does not support the implication of the title, that police picked journalists intentionally, and more supports my point that journalists were caught in the process.
