The actual statement that half the registered firearms in the RWRS have not been re-registered is correct, but it's necessary to fully understand our critique of that. It's not that the system has lost visibility of these weapons; it's that the old database was quite inaccurate, and by re-registering these weapons the accuracy was improved. So for half of them, the data is not up to the same quality as the renewed data.
