When I think of undocumented immigrants, I think about families. According to the study below, some 850,000 of the current undocumented population of the US (which they estimate at around 11 million) are children. We know that other immigrants are working to send money home to support their families in their home countries. Many are fleeing from life-threatening social and economic instability. The current policies are very cruel, and are adding stress to a group of people that have already suffered tremendously. A major difference between the Trump and Obama policies is in having ICE target people at schools, courts, workplaces and places of worship: in other words, they're NOT targeting dangerous criminals: they're targeting people who are trying to work, live normal lives, and do the right thing, including seeking asylum through legal channels.
