Coinneach, you are right! The Mayors of respectable places would be run out of town if they filed a lawsuit so frivilous as Mayor Morial's lawsuit. I obtained a copy and represented a minor defendant for a short time.
However, Mayor Morial's typical supporters (65%) are mostly illiterate, welfare dependent, and ironically racist urban contemporary types.
It is so bad in New Orleans, that a defendant in a lawsuit cannot realistically defend against lawsuits that are filed in New Orleans where a jury is requested.
This is the reason that all of the major class action Trial Lawyer Sponsored lawsuits are filed in New Orleans. For example, Tobacco, Breat Implants, Fen Fen, Guns, you name it.
