Balko is quoting or paraphrasing a statement from a government official but does not identify who said it, when, or in what context—making it impossible to verify the exact quote or assess its accuracy. The post frames the statement as a threat disguised as policy (that criticism will be met with violence), but without the source material, the underlying claim cannot be independently confirmed. What Balko likely means is that officials are warning of enforcement consequences for resistance to immigration policy, but the framing as 'murdering people' in response to 'criticism' is an interpretation that needs the original statement to evaluate fairly.
