RALEIGH, N.C. -

In the last month, Wake County detention officers have interviewed hundreds of inmates and started deportation proceedings as part of a program called 287 (g).

Some call it controversial because many advocacy groups say it can be used to unfairly target Latinos.

Thirteen detention officers have been trained for the program and have limited immigration powers.

Sheriff Donnie Harrison said that his biggest frustration is that dozens, if not hundreds, of the inmates booked into his jail have fake identities.

Joining the 287 (g) program is a way Harrison can figure out exactly who is being booked into the Wake County Jail.

“If there is a discrepancy on your date of birth, or you're being vague with us, or you just won't answer us, and you can't speak very good English, you'll probably go up to 287(g),â€
