JMO on the matter, with my personal belief aside - even if I were to believe RL could possibly be BG, I wouldn't see any point in trying to figure out if he actually bought fish, what he was wearing, what he said/didn't say to LE, etc. The reason being, I don't think there's anything I could find out about him that LE doesn't already know by now. On top of this, I also think, at this point, LE would probably have determined if BG is RL. So, I don't think not looking into those things would matter now, since either way they've investigated him, searched his property and he's on their radar. On the other hand, with LE not saying they have someone specific in their sights, it's possible they're still in need of the public's help in identifying and finding the .because of this I personally don't want to be set on any certain person right now, not if there's chance I could be wrong and I would hate to think of there being people out there who may know or find out something but ignore it because they think LE has him.
BTW, no disrespect intended towards other opinions, we're all free to believe what we want and share our opinions on here and this is only the way I look at it.
MOO
