Lesbian Nana aka PC Emily Bradshaw is a danger to the public and has already physically harmed at least 4 innocent people - and that is all that has been caught on camera in two incidents. She deserves condemnation. She is in a position of power which she has been filmed severely abusing, twice. She has got away with it entirely at least once, and will likely get away with this as well. The public are entitled to feel safe from police, and to know they won't be abused by a power-tripping narcissist. Therefore this is in the public interest to have widespread media attention, and to increase pressure to fire her.
To reiterate, she called 6 male police officers as back up to falsely arrest a 16 year old autistic girl for a homophobic public order offense, which was neither homophobic nor said in public. She repeatedly said "I don't care" when informed that the screaming child punching her own head was autistic. This was a hate crime.
In this latest incident, she actively approached innocent onlookers to pepper spray them in the face - something which causes the eyes to severely burn for up to an hour, and can have negative side effects. Pepper spray is only supposed to be deployed to prevent violence, and they are supposed to be given a warning; Lesbian Nana gave no warning at all, and the people she attacked were either not approaching or were actually already retreating. None of them appeared to be involved in the incident or at imminent risk of being violent. They were just onlookers who she didn't want there. It was quite simply assault.
Anyone who commits a hate crime against a disabled child, or commits assault on random innocent people, deserves to be publicly condemned. This "shaming" as you call it, is far less than she actually deserves, which is the sack and criminal charges.
