Only a hypothetical question (series of questions), but I've heard that taking a bribe is illegal as of the moment the bribe is received. Since the source in question is far from a legal expert, I'm curious about how this actually works (in theory and in practice) if someone were to attempt to take a bribe for the express purpose of securing the evidence (so that the one offering the bribe can't deny it).
Now this is obviously making some assumptions about the nature of the bribe (it would be different if it were, say, a fancy watch versus a paid trip to a resort or an overly expensive dinner), so there are a few scenarios I'm curious about.
If a physical object is offered (a watch, say) and accepted, could the bribe then be taken to the police immediately after without repercussions, or would even that be no good?
If an event of some sort was offered, could the bribee attend while collecting video evidence? I assume this would be strongly discouraged as a form of vigilantism, but would it be illegal in theory? In practice?
Straying further into the absurd, I'm not at all sure if undercover police are in the habit of offering bribes, but if you accepted such a bribe (say, again, a watch or other expensive physical object), then when would the truth come out? Would they arrest you on the spot, or wait to see if you contacted authorities about it? I'm guessing it's pretty hard to run into this situation by accident, or that this isn't even something that happens (or that it happens much differently than I'm imagining).
I'm guessing that the entire reason why this sort of thing is so inadvisable is the obvious chance of misunderstandings, but I'm curious what the real-world results would be of these hollywood-esque scenarios.
