By contrast the workers themselves signed up for some of the most brutal/specialized farm work (which they may not have understood had they lied and never actually done it before - it's one of the highest paid crops for laborers), zero witnesses to their claims (and in fact they could only get 3 of the 17 workers to even claim that they were fired), and were able to carry out a freeroll for a crop year of salary by saying 'Yeah uh we were fired.' Anonymously. Through a translator. Provided by some NGO. Online. While in Mexico. At home.
In the end if one has to make a probability judgement, this is not even remotely close. And indeed this is why the farmers are cheering having their constitutional right to a fair trial granted - they're going to win this literally 100% of the time to the point that this is practically fit for summary judgement. Again the only thing particularly weird here are the government's actions.
