Enforcement of borders and laws does not need to include grabbing non-violent brown people at random Home Depots, while they are firefighting, while they are legally attending immigration court sessions, etc.
Those are overrated VISAs and they're nabbing then procedurally. The US kinda knows who they are and have just been lenient for the most part, now they're telling them to appear and arresting them when they show.
The other commenter is very clearly talking about ICE driving vans into the parking lot of Home Depot and such, then arresting (groups of) brown folk or people who speak Spanish.
Those are very obviously two entirely separate issues. And the latter is undeniably related to skin-color.
1. Pointing to Irish people being arrested doesn't mean racial profiling isn't happening.
2. You're assuming that all Irish people are white
3. You've seemingly refuted the point above with this article but your haven't in any way down that the current methods of enforcement are necessary in policing the border. Americans are allowed to police the border, criticism of their methods doesn't change this and citizens of a democracy should be allowed to ask these questions.
