Department of Homeland Security (DHS) Secretary John Kelly has heard all of that criticism from Americans who are upset at the way his employees treat them and other people, and he has a response for all of you ingrates: Shut up.
If you've ever dealt with surly Transportation Security Administration (TSA) staff who treat you as though you work for them and not the other way around, such behavior goes all the way to the top. In a wide-ranging speech designed to reinforce President Donald Trump's attitude that America is under siege, Kelly spoke told an audience at George Washington University and pretty much told them that without the aggressive approaches of the DHS we'd all be murdered by drug cartels and terrorist groups. So can it with the criticism.
The whole speech is watchable here at C-Span for the so-inclined. His speech was essentially a combination of every single post-9/11 security state speech combined with every single '80s and '90s drug warrior panic speech. The media responses are highlighting his defensiveness to criticism.
