I can give you the answer with regard to the need for facial recognition: for the simple reason that, when somebody is disruptive in the House, that person may be banned from the parliament for a period of 24 or more hours, and, to know if that person is attempting to re-enter the parliament, there is a need for facial recognition. None of the other groups, to my knowledge, had a problem with facial recognition.

Opposition members: But they could disrupt the parliament!

The question is recognition, and also there are a number of people who are banned from this parliament who need to be recognised, as security issues.
