I know you were replying to someone else but speaking just for myself....I think Chadwell is the best candidate that we have seen/know about (there may be better ones LE have privately; they certainly know more than us). There are some valid reasons he could be the one. And if he is, then it's a good thing...the victims' families could be at rest.
However, my hackles do rise when I see posts inflating his possible connections over what has been confirmed by LE (because I think anything posted here should be as accurate as possible).
And while I like seeing others' opinions about his possible involvement, I don't like seeing opinions stated as fact because I fear that any person who DOES have important information may not come forward to LE if they read false information or take rumors and opinions literally. This goes for any case on Websleuths though, not just this one.
Any hostility you get from me is more about people being irresponsible with the information we do have than anything to do with JBC or any other potential POI. Again, that's just my personal take on it.
