No. The quote from Shep was a misquote. They weren't "locked" in, the road was blocked. Two completely different concepts.
Don't think any authorities would lock people in & risk a fire or other trouble a la New York Triangle Fire. Thus why I thought Shep was exaggerating
He spoke of it as a check point where people were turned back.
And with this Fort fumble operation I wouldn't put anything past the authorities.
I think what it happening is Sheriff Harry Lee has put his foot down and is not allowing the thugs to come into Jefferson Parish. Gretna is not in Orleans Parish. Harry Lee does not put up with those thugs crap. He point blank said he would just as soon shoot them than to arrest them. What you guys are seeing is Orleans Parish on display, not the rest of the Greater New Orleans area.
