Clearly we need to process these kids through so they can either become "lost children" or send them back after interrogations to determine any relations to Mexican gangs, so the Mexican gangs can then deal with them. That was policy numerous times under the previous administration, and apparently that was okay, because we never heard anything about it from Perpetually Triggered LibBot nation.
Or, route #3 which is catch and release, and then deport those claiming U.S. born children. Happened thousands of times in the past, and again, apparently that was perfectly fine because we didn't hear a word about it from Triggered LibBot Nation.
