Look up the Latin term "pro hac vice." Means "for this occasion only." It's an exemption given lawyers who are from out of state and not admitted to a state's bar that allows them to work on a case in that state. As states have different laws the lawyer in question would usually work with a local attorney. We have all seen famous cases where prominent lawyers are hired to represent famous clients with the lawyers coming in from other parts of the country. Alan Dershowitz of Harvard fame, for example, representing O.J. Simpson. At any rate state laws don't supersede the Constitution so if a person has a 1st Amendment right to video someone then lawyers from any state can rightfully point out he's protected by the Federal Constitution.Hold on here. Based on your posted text it would appear that it's you who is texting with a Nevada licensed attorney claiming to be the affected individual. If so then you are claiming under false pretenses, Furthermore if a case comes out of this matter it would in all likelihood be tried in a New York State court. If your attorney is not licensed to practice law in the state of New York it is highly unlikely that the state of New York would allow your unlicensed attorney to argue the case in front of it's state court. If so then what your attorney has to say about the matter doesn't mean a thing.
As I said before the odds of the affected worker getting redress were not good but at the same time not impossible. If a state of New York licensed law firm sees Mr. White's actions as one that cannot be defended as a First Amendment case they might take up the matter. You can't always just go on your merry old way doing whatever you damn well please to any person you chose to then just run away and hide behind the First Amendment.
P.S. If you listen to the video you can clearly hear the boxes hitting the floor of the truck. The best way to make sure you don't get fired for violating company policies is to not violate company policies.
