Re: Who arrests the watchmen?
" "...later seizes hold of Noble's camera tripod and refuses to let go of it..."
"...The police spokesperson continued: “No offence has been reported ..."
Well an offence certainly seems to have been committed, one that the officers were clearly aware of. Nulfeasance in public office anyone? "
Did the photographer make an allegation? That is the key; the alleged victim must make an allegation, unless something physically serious - violent assault, theft of or damage to property, including images - has taken place, in which case they are bound by duty to intervene for the public good.
