I can tell the weasel comment really got under your skin, likely because you know deep down there is truth to it. There were numerous instances last year of protestors aiding and defending illegal immigrants from ICE that they specifically knew were convicted child rapists.
"many innocent are presented as criminals" being illegally in the country is a crime. End of story. They were (and still are) giving people free tickets home and cash bonuses to leave the country on their own terms and self-deport. No country is obligated to host illegal immigrants.
