The repeal of 'Don't ask, don't tell'

LGBT servicemen and women in the US armed forces had to keep their sexuality secret until the 'Don't ask, don't tell' policy was repealed in 2011. Lieutenant Colonel Heather Mack served under the policy for most of her military career. She spoke to Rachael Gillman about her experiences. This programme is a rebroadcast.
