I wish that we would let more people in legally so at least we would know who is here, and their background (so they wouldn't be sneaking across the border instead).
In the meantime, however, if you are breaking the law, you are breaking the law, it's awful that these arrests happened in front of children, but people get arrested in front of their kids all the time, whether it's for crossing a border illegally, or holding up a gas station, it's unfortunate, but the parent brought it onto the family by willingly breaking the law.
