Many responses simply point out that the unaccounted-for 1472 unaccompanied kids are a separate issue from new Sessions family separation policy. Literally true, but past is prologue & IMO we need context on UAC policy to fight this.
Obama's response to juvenile "surge" (2012-2014) was bad, as many of us tried to explain as it was happening. Also important context for crisis Sessions family separation policy will inevitably cause.
There are several variations on this take, but I agree. Pushing Trump to "fix" a fact-deficient media-imagined crisis only gets us significantly worse policy
