Yes, he did unleash a lot of criminals (wouldn't say hundreds), but the world government would also take into account that was not his intention. And as far as we know none of these criminals are that great a threat, and the marines would've already easily been able to capture most of these criminals by the time they start issuing new bounties. The criminals released from Impel Down were pretty the world's biggest criminals, as opposed to the criminals released by Usopp. Once again, based on the action alone it, all he did was knock out a little girl. And that action doesn't make him that great a threat to the World Government, cause I don't think all those criminals he released will pose that much of a threat to the World Government (especially in comparison to Impel Down prisoners)
