if that was a black and white still photo of vintage police, it would be "charming", a look back at a more "inocent" age. and likley used on greetings cards and ikea prints!
i make no judgement one way or another , but did they deserve a reprimand for using a plastic sledge shaped object for a brief mess about? this behaviour would be the norm with any group of workmates, we just expect a little more restarint from our police.
for me more disturbing is the fact that anyone can be filmed, anywhere doing anything these days on a camera phone, and seconds later be on youtube without consent.
