Right now, whether the guns were kept out in the bedroom or stored somewhere more secure, I'm not considering them relevant to finding Lisa.
If we find out that the guns were kept out because the family was involved in any risky activities or had been threatened, then I think that opens up a whole new set of possibilities as to what went down that night and what might have happened to Lisa. Nothing like that has come out in public from the parents, other witnesses, or LE. But, imo, there's a lot we still don't know.
The guns are the back burner for me right now. Something that may or may not come into play as more facts become known.
JMO...
I agree, they are irrelevant to me. Some are using (or trying to use) a theory that guns out in the open of kids = bad parents when it is not a fact the guns were kept out in the open.
