Look for yourself, but 86, 94 and 2006 Various Acts, all cover the definitions, if you look back at twitter he is actually quite careful what he says and maybe the reason he has actually avoided a prosecution.
"racist thug, bang him up and throw away the key" tendency appears to be discounting his criminal conviction history, including assaulting a police officer. I suspect that if he was a Muslim with the same rap sheet you'd want him banged up for longer.
The CPS uses definitions agreed with the National Police Chiefs' Council to identify racist or religious incidents/crimes and to monitor the decisions and outcomes:
"Any incident/crime which is perceived by the victim or any other person to be motivated by hostility or prejudice based on a person's race or perceived race"
"Any incident/crime which is perceived by the victim or any other person to be motivated by a hostility or prejudice based on a person's religion or perceived religion."
Is that what I am is it, why not go the whole hog and say that I am "literally Hitler". This type of race baiting goes right past me these days, those words get thrown around like mad woman's shite in lieu of argument and I don't give a fuck.
PERSON and perception are the operatives, they could make a complaint, but the police and CPS have to prove its personal. If you notice, he is very careful to only target Muslims who are convicted, he never just picks out a random muslim and shout abuse.
When he does his walks through a town, he takes plenty of abuse, then returns it, but never fixates or dwells on a person.
