<Snipped quote by Lucius Cypher>

Shiro is a loud blabber mouth. Doesn't like talking about himself, but the pages to his book can somewhat be easily cracked open. Looks like Shiro might be alone in stopping his teammates.

Abel doesn't like seriously fighting other people, and would prefer a noncombat solution when a situation is as ambiguous as this.  Add in his injury, and he's not anxious for another scrap.  So he'd side with Shiro.

What could happen is that Gren gets in among the guards and starts wiping them out.  Ignorant to the compliance status of Shiro and Abel, they'd think that the situation would be beyond diplomacy, and start releasing animals before going into retreat.  Pop, after his battle with Sapphire, depending on his injury would either be captured or able to flee via speedboat with his family.  That way the ambiguousness of righteousness remains, but the Shelter people are at a disadvantage, no permanent damage among SASG occurs, and the authorities can be called in to deal with the remaining faunus and things.
