well, it worked in VEGAS, didn’t it??? NEVER SOLVED! Typical of the FBI.....they are PATHETIC!
It depends what you mean by “solved”.
IN one definition, we consider a case “solved” when we are able to apprehend and prosecute the perpetrator. “Unsolved cases” are those where we don’t know who did it, or can’t find them. “Failed cases” are those where we think we got the person, but we can’t get a conviction.
In Vegas, and here, we have the perpetrators, they are both dead, so they have been “punished” as much as we can, although people will also sue their estates, which is more of compensation than punishment, since a dead person doesn’t really care what you do with their money.
I think you mean “solved” as “we know exactly why they did it”. We OFTEN don’t know why people do things, we just guess that the robber kills the store owner because they wanted the cash, or because they thought it would be fun, we guess why a rapist picked a particular girl, we try to resolve why a serial killer chooses to go on a rampage.
But often we simply don’t know. I watch a cute youtube broadcast every week called “murder mystery and makeup monday”, where the woman does her own half-baked research into mostly serial killers; and what you get from that is that we hardly ever REALLY know why they do what they do. Not many people write manifestos.
