Okay, if they're asylum seekers and have valid reasons for claiming asylum, why are they trying to "hide" after crossing such that we're here discussing ICE, border camps, etc? Most of the crossers aren't "technically" asylum seekers and more like economic migrants trying to look for a better life. They probably know this and so hide from border officials. So one side of this debate wants to "include" economic migrants, and the other doesn't. If we can resolve this particular point, we can cut through all the hyperbole and emotion regarding the topic.
