A man and his wife sneak across the border illegally from Mexico. After they live here for a couple of years they have a couple of kids. The kids are now age 9 and 13 and have lived here their whole lives. They don't speak much Spanish. They are enrolled in school and like all kids have friends and play sports and so on. The parents however have never obtained legal status despite the fact they have lived and worked here for 15 years.
It's entirely up to you, could you personally walk into their home, arrest the parents in front of their kids, bring them up before an immigration hearing where you sit as judge, and then deport them back to Mexico?
