Life is also cheap to many people in high places on this side of the border. We don't have the high ground to call out Mexico's disregard for the poor, especially nowadays. Ask the children in those detention cages. It's not just immigrants who are vulnerable, either. Ask anyone in Flint, Michigan.
I doubt any shady U.S. operatives south of the border would be too worried about a mildly successful rapper who hasn't been relevant for 20 years, but calling out ICE like that, when residing in an environment with such vulnerable security, at least raises the possibility.
