Come on; a 5 foot something, 8 stone woman, against a 6 foot plus, body armoured up bloke twice her weight?? And he felt 'threatened'? Do me a favour!
I wonder how many people posting on here have had urine thrown at them, been spat at, had bleach squirted at them and so on and so on. Those things are fairly routine for officers on this kind of duty.
The situation here is very simple. There is an absolute right to protest, no question about that. There is however no reason to riot nor to disobey a reasonable request or instruction from a Police officer in the course of his duty. This woman is clearly being extremely aggressive and provocative, and having been told to sling her hook several times persisted in having a go at the guy in a very volatile situation. The fact that a small female is having a go at a large tooled up bloke in body armour tends to indicate that she is either potty, or looking for a PR success. The reality here is that she clearly got the latter, and that is entirely regretable IMHO. As stated previously, I object very strongly to the fact that my civil rights are being eroded and my right to protest has been diminished, but not by the Police, its prats like her who are doing the damage.
Watch the clip and look what the copper does afterwards. He totally ignores her, and immediately returns to scanning the crowd and to controlling the situation. i.e. he has neutralised the threat and is getting on with his job. If he is in fact being investigated for other issues, I can assure you he will have thought very hard about his actions, especially being fully aware that every second of it would be on camera. His career and potentially freedom would depend on it and he will be judged much more thoroughly than she ever will. Not only in court, but independantly of that by the force, and probably also involving the Police complaints authority.
