At least 2,000 children have been separated from their parents since the Trump administration last month implemented its “zero tolerance” policy for prosecuting illegal border crossings. The tactic, which critics have described as “inhumane” and “immoral,” has drawn condemnation from human rights and religious organizations, which organized demonstrations across the country calling for the families to be reunited. Under the policy, many parents face criminal as well as civil prosecution. Because children couldn’t be jailed with their parents, they were detained separately.
