I'm glad the CCTV has been released.
Reading the opinion of some are just terrifying. The video shows extreme violence towards another human being (police officer) yet he is the one that is blamed for this situation.
The officer is at the airport carrying firearms for the protection of the public. He has had blows reined on him to his head multiple times and repeatedly - all of this whilst he is carrying a firearm that could be discharged at ANY time and not by himself. The multiple blows to the head, combined with the concern for his firearm being used against him and also other innocent members of the public (could be you or I with our kids coming back from Benidorm), must have been absolutely fucking terrifying. At that point this officer is fighting for his (and our) lives.
...and for only 45k per year I must add.
What happens next must be left for GMP to investigate.
To those posters who say that perhaps better communication could have been given beforehand/they went in heavy handed/there's something wrong with the quality of the training - apply to your local police force and offer up your services and impart your knowledge and experience of dealing with the most violent people of society.
