At least with regards to U.S. law, your untrained legal analysis isn't much smarter than someone trying cave diving without training.
Well...I'm not from the US. I just thought you guys shot everyone...
I don't think he was going for analysis so much as analogy.
An accurate thought

If you see someone clearly unqualified in a cave, you assume they're attempting to commit suicide (because in reality they are ... whether or not they realize it) and you respond as you would to anyone attempting suicide ... which in a decent world would be to try to prevent them from succeeding ...
Yes, that's an analogy I was trying to make. It'd be an 'intervention'. Before Lecter gets the wrong idea....I don't know how US law dictates upon that..
Not kinda like that. The police are called, employees are strictly told not to physically confront anyone in fear of lawsuits
Ok, maybe Walmart was a bad analogy (I was trying to keep it in line with the earlier comment made).
How about substituting: "a bar or nightclub". Such businesses do permit employees to use physical force to remove undesireables, especially those who create a risk to themselves or others... i.e. bouncers.
Example:
Patron enters a bar and consumes alcohol to the point of inebriation.
Patron wishes to continue drinking.
Bar has policy 'no drunkenness', as it wishes to safeguard patron's health, its own liability and prevent obstruction to its business activities.
Bar Tender refuses patron further alcoholic beverages and instructs him to leave premises.
Patron refuses and continues to demand further alcohol.
Bar Tender calls Security, who then reiterate the bar policy to the customer and, again, instruct them to leave the premises.
Patron still refuses.
Security removes patron from premises using minimum force.
Analogy:
Diver enters site and goes for a dive.
Diver enters overhead environment, for which they are not trained.
Site has policy 'appropriate training and qualification', as it wishes to safeguard patron's health, its own liability and prevent obstruction to its business activities.
Site has communicated this policy to regular visitors and through associated cave agencies - requests vigilance/intervention to enforce policy.
Site has further communicated this policy by placing warning notices at the entrance to caves.
Observer refuses diver further entry into overhead environment and instructs them to leave the cave.
Diver refuses and continues trying to move further into the overhead environment.
Observer removes diver from the overhead using minimum force.
There's a difference between labeling your property as private property/ no trespassing and then taking enforcement into your own hands, I'm afraid. Not at all the greatest example of the owner of a cave frankly because assuming they knew about everyone entering their property/ getting permission granted (under the operating assumption that they tell others to wag the finger or enforce their rules while on it [wtf?]), they are then responsible for those who are on their grounds, tourism or not. If you're letting unqualified divers go knowingly, then you truly do open yourself up to lawsuits. This shouldn't fall on those enjoying the owners property to enforce every aspect of it.
The owner has ultimate right to dictate who does what, when and how on their property.
The owner can set conditions on entry.
The owner can enforce those conditions.
The owner can delegate enforcement of those conditions to others.
Another analogy: I go to Disney World. On a roller-coaster ride, I proceed to remove the retaining mechanism that holds me in my seat. I want to ride 'free'. Upon noticing my actions, the ride attendant (1) stops the ride and (2) asks me to get off and leave. I refuse in the belief that it is my right to ride how I want and take the risks that I feel are appropriate. The ride attendant calls security, who force me to leave the property.
The difference between cave diving and other premises, is that an observer in a cave will have the knowledge that the police cannot be called to attend the immediate scene in a sufficiently timely manner at to prevent harm from occurring. Consequently, there is a reasonable belief that if personal action is not taken, harm will occur.
As mentioned, I'm not familiar with US law (you can't just shoot them?). I do suspect that citizens have rights to use reasonable force to uphold the law. In the UK, you can enact a 'citizen's arrest', using minimum and reasonable force, in the absence of the police. In fact, as I understand it, the UK police have no greater provision of 'rights' beyond any private citizen. What they can do, anyone can do.. including removal from private premises or detention for the safety of the individual or others.
