My family, friends and I like watching the Border security documentary, but was disturbed that Sydney Airport masked people's faces. The masked faces will never be identified by the general public, especially in the services and retailers. Masking is tantamount to agreeing with potential wrong doers and so encouraging the behaviour of wrongdoing. Please reconsider not to mask people's faces because the purpose of the exercise is nothing to hide is equal to freedom of expression of travellers and residents. Stand up for Australia and not for potential criminal behaviour.
