Lets recap on the facts that we do know:
1) No news article containing the words Louisiana, Sheriff, Deputy or Parish is ever an article about something good happening
2) Lifting off in the dark at 02:26 for a high-speed low-level car chase in such a rural area is probably not a great idea in any helicopter; particularly so in a small light civil helicopter
3) Helicopter forums are not the best source of information re legal matters
