A Wall Won't Fix This

A review by The New York Times of thousands of court records and internal agency documents showed that over the last 10 years almost 200 employees and contract workers of the Department of Homeland Security have taken nearly $15 million in bribes while being paid to protect the nation’s borders and enforce immigration laws.

These employees have looked the other way as tons of drugs and thousands of undocumented immigrants were smuggled into the United States, the records show. They have illegally sold green cards and other immigration documents, have entered law enforcement databases and given sensitive information to drug cartels.

The Times’s findings most likely undercount the amount of bribes because in many cases court records do not give a tally. The findings also do not include gifts, trips or money stolen by Homeland Security employees.

“It does absolutely no good to talk about the building of walls or tougher enforcement if you can’t secure the integrity of the immigration system, when you have fraud and corruption with your own employees,” said an internal affairs official at the Department of Homeland Security who spoke on the condition of anonymity.

Bingo. And why does that statement require anonymity?
