I agree, however, the organization that the warrant needs to be served too and the people within the organization it needs to be served too, like the lawyers, needs to be abundantly clear from the registry information. Law enforcement, or anyone else for that matter, shouldn't have to waste the judges and the courts time getting warrants reissued multiple times because the registry says one organization controls the addresses but the addresses were (re)allocated to some other organization who is the one that knows the real user and needs to be named in the warrant for it to be valid. Or that the addresses are used in a different jurisdiction and a different court needs to issue the warrant for it to be valid. 

The registry shouldn't be a substitute for getting warrants. However, the registry still plays an important role in the process of a court properly issuing a valid warrant.

Therefore all allocations or reallocations need to be clear in the registry. I believe assignments should only be recorded in the registry if they are made directly from the RIR or if requested by the entity receiving the assignment. Also, an optional Legal POC might be useful to direct legal service to the proper place in an orginization.
