I'm not quite sure of the point you're trying to make. Donahue is arguing that adopting CCW laws in high crime, drug infested urban areas would increase crimes such as crack shootouts. This is irrelevent since criminals, particularly crack dealers, would be highly unlikely to apply for, or be granted, CCW permits. In effect, he's arguing that liberalizing carry laws in high crime areas would result in more crimes since more criminals would then carry concealed weapons.

No, that's not what he's arguing. He's just trying to explain why Lott's findings of that CCW leads to less crime is spurious. One cannot argue from the evidence presented in his paper that CCW leads to more crime.
