Infact, this thread is a bit cringeworthy. I'll spell it out in simple terms.
A Yorkshire police officer is told to work at a Huddersfield vs Millwall footbal match, in the Millwall end. The police officer probably knows that Millwall fans have a shocking reputation for violence and disorder.
The Millwall fans are likely to have been drinking heavily throughout the day, and at the end of the game have become aggressive with both Huddersfield fans and the police.
At the start of the clip, you see the officer shoving the bloke away lightly, basically warning him to stay back. The officer does not know this bloke, and does not know what risk he carries, is he known to sneak weapons into football matches? Who knows?
Anyway, the bloke advances towards the officer to within 6inches of his face. He is (I think we can all agree) shouting in his face, probably swearing and basically just acting in an aggressive manner. The cop's options at this time are:
1- Stand there and take it. Try warning him probably for the 100th time to get back from his face. Wait and see if the guy becomes violent, bearing in mind the officer is facing backwards in the middle of a set of stairs. Why should the cop wait to be "hit" first? That's not their job.
2- CS Spray - this will only ignite the situation, and not a good idea to use it inside a football stadium. Plus, the situation is taking place on the stairwell so it's not a good idea to blind folk is it?
3- A baton strike - Probably seen as a bit heavy handed, and will cause the Millwall "fans" to stick up for their mate and again ignite the situation.
4- A open hand firm push to the face. The guys already been warned and been pushed back lightly. He's becoming more and more aggressive advancing towards the cop, an open hand push to the face lets him know that the cops don't have to put up with that shit, at the same time forcing the guy away from the officer.
Result = The guys mates hold him back. The cop is now at a safe distance from the aggressive "fan", nobody's blinded by CS or badly injured by a baton.
Verdict = Correct option. Safety ensured, the cop was well within his rights to do what he did. He's a human, not a ninja or a football hooligan control expert.
Some of these "what did the Millwall fan actually do" and "police bullying" comments are laughable, for god sake take of your anti police specs and watch the video. Would you put up with a guy getting right into your face, shouting and swearing at you? No you wouldn't.
