Comment 1 for bug 1847552

This is still the case in 3.10. The permission for needed for checking in an item that was marked lost is COPY_ALERT_MESSAGE.override, which is the same permission needed for checking in any item that has an alert attached to it. I don't know if that's the desired behavior, or if it should be similar to the process of checking in a claims returned item, which requires both COPY_ALERT_MESSAGE.override and CIRC_CLAIMS_RETURNED.override.
