This speculation based upon very vague and quite limited news reporting is a waste of time particularly re the criminal charges which at best is a collateral issue to that of the focus of this thread.
What say we get back to the issues that deal directly. with the crash of the helicopter and the loss of two Police Officers who were the crew of the destroyed aircraft.
I posted a link to the Louisiana Statute that pertains and it is quite clear in its text....the Prosecutor has filed charges (based upon information not contained in any news report) and all of that shall be dealt with by the Louisiana Criminal Justices system.
As to the crash....remember the crash....it will be investigated. by the appropriate authorities and some resolution of those issues will be made.
If you are going to pontificate upon the causes of the crash do try to add to the discussion rather than run off peering down Rabbit Holes.
The circumstances surrounding this crash are interesting and worthy of discussion but what say we do so with some clear of focus of what we discuss.
Our frame of reference has to be with the Rules, Regulations, and Laws that pertain to this specific tragedy.
Lets start with it was a "Public Use" aircraft and operation which affords the Operator a much more flexible set of Rules by the FAA.
That shifts a bigger burden onto the Operator as a result as regards to safety practices and the like.
Legitimate questions exist re fitnesses/suitability of the aircraft, crew, and operational control.
Those are sufficient io hold our attention rather than trying to play Clarence Darrow or Aticus Finch over related but irrelevant issues to the actual accident and its causes.
