According to the article DHS had nothing to do with it. Texas and the FBI/DOJ were running this operation.
Actually DHS is quite limited to which laws they can enforce. DOJ owns domestic terrorism unless there is an immigration angle to the case.
DHS spends their time releasing illegal immigrants, seizing counterfeit products, looking through underwear at the airport, kiddy porn and writing intel briefings nobody but the media take seriously.
And yet the DNCmedia is playing up the horror show that will occur if the Republicans delay further funding of DHS just because of Obama's amnesty program for illegals.
Same thing.
