All girl gangs isn't a new concept. It's a concept that's been done before in the past. There was always a way to get an all girl gang started. And yeah, teenage girls were capable of forming all girl gangs way back in the 1930's. Few if ever paid attention, but such a concept was possible even during the Great Depression. It's just a few chicks hanging out with each other to cause mischief as the Stock Market falls to rock bottom levels. Somebody has to hold down the fort as the Great Depression wrecked the United States in the 1930's. It might as well be an all girl gang to get the job done. Oh yes, they looked good doing so too.
