Alabama is a fairly regular shape. Draw a line down the middle from north to south. Draw 2 horizontal lines east to west making six districts of equal square miles. Make a 7th district out of the bobtail.
Now adjust those lines north/south, east west until about 750,000 people are in each district.
Make the decision by geometry primarily and population secondarily, and no one can accuse you of anything.
ANY one can be accused of ANYthing at almost ANY time.
...but then they should have to PROVE it.
