Apparently, what happened was that this journalist had witnessed that Morales, Salguero had seen Galindo's brutal arrest but hadn't done anything (which sounds pretty obvious if they were the ones who'd given the order). Salguero threatened the journalist claiming that, if she stuck to those facts, she would then have to contradict Morales' and hers at court - “tu palabra estará contra la mía y contra la del Presidente”.
The day after, it was all in the news. That was such a silly thing to do.
