The head of the U.S. Border Patrol testified to Congress that less than half of the southern border is under “operational control.”

Brandon Judd cited violent conditions as part of the problem and added that one out of every five people caught attempting to enter the U.S. has a criminal record in Mexico or the U.S.

In 2014, the border patrol caught around 486,000 illegal immigrants, but only 91,000 were returned to Mexico.

“This is the challenge we are facing at the border today. There are those who will point to lower apprehension rates and tell you the border is secure. Border Patrol agents, however, throughout this nation will tell you the border is not secure and the southwest border certainly is not safe,” Judd testified.

Judd also said that drug cartels are a major issue.

“These cartels are well organized, heavily armed, and pathologically violent. To give you sense of the violence the official death, as quoted earlier, toll from the cartel violence in Mexico is 60,000. This is more than the United States military lost in in Vietnam. However, the unofficial death toll in Mexico is over 120,000 killed and another 27,000 missing and presumed dead,” Judd said.

“In Mexico, the cartels kill without hesitation or fear of prosecution. In May of this year, cartel members shot down a Mexican Army helicopter in the State of Jalisco. Why would we expect them to behave any differently on the U.S./Mexico border?”
