Does a person need to be convicted of a state crime for officers to use the 287(g) authority?
Officers trained and certified in the 287(g) program may use their authority when dealing with someone suspected of a state crime that is more than a traffic offense. If the person’s identity is in question, the officer will be able to make an inquiry to the ICE system for help in making a positive identification. Officers can only use their 287(g) authority when dealing with persons suspected of committing state crimes and whose identity is in question or are suspected of being an illegal alien. While enforcing immigration law is primarily a federal responsibility, the 287(g) program provides a mechanism for enlisting the help of state and local law enforcement in this effort with a minimal impact on their normal duties.
