Why give people caution plus 3 interviews instead of just arresting them?

[justbeenaccused]

i.e. why caution plus 3 and then arrest them afterwards, instead of just arresting them up front

Why do you keep starting threads?

cos Im obviously worried

But starting numerous threads isn’t going to help you

Lean on the legal advice that you've said you've sought.

Surely your solicitor is the best person to answer your questions on your racially/gender/sexually aggravated situation.
