Officers get to be tricky
The problem here is you're expecting the TV enforcement officers to deal fairly and not pull dirty tricks or be manipulative.
There's no legal obligation for them to do that, just as there's no legal obligation for police detectives to not trick you.
There are limits to what you can do, but this is where we get into the difference between law theory and law practice. For instance the folded-over document that you sign without realizing what it says. On one hand, the judge sees a deadlocked squabble over what was done, between a suspect and an enforcement officer. On the other hand the judge sees a document plainly signed by the defendant. The document will tend to prevail. The entire basis of contract law is that a signed document has weight, and it follows that everyone who signs a document has a duty to know what they're signing. It wouldn't do for every signer who has remorse to simply claim to be misled! So the "tricked" argument is unlikely to go far.
Know your rights.
When an officer asks for permission to search your home, that is because they do not have the right to search. When police have a right to search, they don't ask. So the very fact they are asking means you can say no. And should: It does not benefit you in any way whatsoever to allow the search, it can only go against you.
They may say you can't refuse, and then ask again for permission; still say you do not consent. If they had a right, they wouldn't be asking.
Likewise you do not have any obligation to answer any question, except in certain rare instances. Again, cooperation does nothing for you and can only possibly hurt you.
When an officer is manipulative, to try to make you "FEEL" a particular way, that is quite on purpose, for the sole purpose of getting you to do something that is not in your own best interest. Of course, the emotional impulse to act is very high; that's the whole point of manipulation. That is why you must be absolutely scrupulous when dealing with authorities to follow the "rules of engagement" as advised by civil rights groups or by your lawyer.
Part of the manipulation is to tempt you into saying something "smart" - you know that urge - but again that cannot help you and can only hurt.
Protecting yourself from such manipulation is exactly why you engage a lawyer for a serious matter. For TV goons, just don't speak to them at all.
