You do not have to answer any questions.

An alert will be available within your APP that you can open if you are recording and filming your conversation with the police on your mobile.People within a certain radius will be able to monitor your situation on their phones and can then make a decision on whether they wish to make themselves available to bear witness to the proceedings taking place.
