“Dismantle” and “abolish” are about equally popular in the movement for those that support the position that goes beyond “defund” in organizational change.
And 39% is widespread, though obviously not majority, support (and “defund” has 76%—a large majority—support in the pool, which I notice you ignore completely.) And nothing in the quote (or the movement) suggests that whatever armed law enforcement functions were retained would be concentrated in a single new organization created ex nihilo. While, again, advocates are mostly calling for a community process to rethink a design new service delivery and public safety systems rather than selling an already completed redesign that just needs legislative blessing, one framework concept I've seen mentioned more than once is redistributing domain-specific law-enforcement functions within service agencies consistent with the agencies’ domain, broadly the same much state and federal law enforcement functionality is rather than being concentrated in a single paramilitary force of general remit.
