Zola's case went ot court this week as she refused to accept the caution but it has been adjourned because (don't laugh ) because the inpsector dealing with her case didn't know what questions to ask her and had to get permission from her superior before speaking obvioulsy they had expected her to accept the caution and hadn't bothered to prepare the case against her
As far as the CRB check goes i don't think it counts RSPCA are only an animal charity..they have no powers of arrest caution or anything else so a "caution" is just some thug in a meaningless uniform giving you a telling off like a naughty schoolkid
As in Zola's case , she has been asked to go in again to accept a caution (3rd.time) she is undecided about going in or not
Hope reading through her case will be of help to your friend.
Remember that they have NO POWERS..they are not Police and make sure that you psread word of this fact around as the more people aware of this the less power they have to lie falsify evidence cheat seize pets they are just a bunch of pOwer crazy SCUMBAGS
