T-Rex: It's TOTALLY LEGAL for you to pay me fat stacks in exchange for a legal service I provide! For example, you might coerce me into mopping the floors of your supergross nasty restaurant bathroom/hole by promising me money.
T-Rex: I believe this is called "having a job"!
T-Rex: And similarly, if I find out an embarrassing but non-criminal secret about you through legal means - like maybe you're a celebrity having an affair?? - it's again TOTALLY LEGAL for me to tell, or not tell, anyone this secret.
Dromiceiomimus: True.
T-Rex: AND YET, if I seek your fat stacks in exchange for the service of not sharing this secret, I've committed a crime!
Utahraptor: Yeah, that's blackmail!
T-Rex: Correction: that's the paradox of blackmail!
T-Rex: Unlike all the other Major Crimes, blackmail is made of legal acts, and it's only the COMBINATION of these legal acts that's illegal! All I'm doing is offering you a lawful service at a price, which you can accept or refuse without coercion. The exact same thing happens when a kid offers to mow your lawn, dude!
T-Rex: Only when the kid does it it's "not a crime" and he "shouldn't go to jail, mister".
T-Rex: PFFT.
T-Rex: PFFT, I SAY, WITH ALARMING REGULARITY.
