If you have someone bang to rights or catch someone bang to rights, you have enough evidence against them to accuse them of a crime and to prove that they are guilty. You've got your man — got him bang to rights — evidence, witnesses, the lot. There's no getting out if it — they've been caught bang to rights. Note: In American English you have or catch someone dead to rights. How do you intend to proceed in the Rafaelli case? I mean, you have him pretty well dead to rights.
