Argyle ISD Police chief Paul Cairney reminded the public that armed staff members all volunteered and passed a rigorous training.

Cairney said, “There is nobody that is forced to do this. It is not a pre-condition to their employment here in the district by any means.”

He also spoke about how their armed staff policy differs from the Texas School Marshal program in that the AISD staff do not have arresting authority.

Cairney also said unlike those in the Marshal program, AISD staff who carry concealed have their weapons on them all the time.
