The balaclava is a fire retardant in case of petrol bombs and is generally worn where a large confrontation is possible. Nothing to do with concealing identity. Also, and I may be wrong on this, but the public order overalls are stock items and not personal issue, hence no personal ID on the outside.
Strikes me that the image looks worse than the reality. The hired hoods image is one I’m not too comfortable with though. Private security gone up a level.
