What news do you read? Whatever it is, you should consider trying a new source.
Pretty much all news outlets covered their storming of the border in southern Mexico and seriously injuring several Mexican police.
Last week Al Jazeera reported that about six hundred of the caravan were caught and arrested illegally crossing into the U.S.
The BBC just reported that about one hundred of those involved in the storming of the border incident yesterday where the U.S. border patrol used tear gas to repel have been deported by Mexico.
And this, you would say, is a justified use of tear gas?
To attack desperate poor people and their families? I don't share your view of who is in the wrong here. Nothing justifies treating people as dispensable, least of all the interests of a nation that (a) played a large role in creating the conditions of their hardship and (b) have no moral standing to denounce their migration without also denouncing the colonization that established America itself, far more invasive and destructive than anything the caravan could muster.
You know, the United States exercises plenty of leniency and restraint in which of its laws it chooses to enforce and how. Something being illegal is not, in itself, a license for any and all measures of retaliation to be taken against the behavior. Lots of laws are never enforced, or only lightly enforced until they are finally taken off the books. So, I'm not impressed by appeals to the law regarding how to treat fellow human beings who want to live somewhere other than their place of birth. And I'm not scared of poor people who attack police officers. I'm scared of police officers who attack poor people.
