In my opinion....
I think it's easy to take the situations we see on tv or in the movies, along with the more sensational crimes and conspiracies that hit the news, and speculate that these things happen all the time. I believe, in reality, crimes are pretty simple most of the time. It's possible that, with all the speculating we have done here, we might be surprised to learn the facts one day, that DG just went to the L's that night because he heard they were having an estate sale, and thought he could somehow get his hands on that cash, and the situation escalated to violence and murder. Who knows?
I am a very practical, critical thinker. While some folks are comfortable positing theories based on intuition or a feeling, I like to look at the facts as we know them and base my "sleuthing" on those facts. I also think we can become frustrated at the seeming lack of progress in a case, that *something* useful must be done, and so we try to do some sleuthing of our own. I think we all just have a different threshold for theories that seem to be based on a lot of reaching, assumptions not grounded in fact, or feeling. I would fall into the category of having a low threshold for that, but others may feel it is productive. I am a questioner, so I will always want to ask "why?" Like why do you think there are other perpetrators, or that DG is a "patsy" (as someone suggested) or why do you think that wedding band found in the river could be AL's, and so on. I'm using these as examples.
But whether your theories are grounded in facts, or based on feeling, intuition, or simple "what if" thinking, I believe anything said is fair game for others with a questioning mind to say "but why do you think that?" Maybe others will see the train of thought, maybe not. I don't think anyone questions others' theories intending to offend, I know I don't. I just like to ask questions when a theory is proposed - why do you think it's a biker gang, why do think DG was still manufacturing drugs, why do you think NO is still alive, etc.
I apologize in advance if anyone feels ever offended when I ask questions. I always try to be diplomatic and keep the peace so the discussions can be fruitful and friendly. Sometimes we just have to agree to disagree.
