Yes, it is a lie. DB claims that LE made up the cell phone pings they showed her because it wasn't possible for the phones to dial out because they were restricted. This is what she said. Do you want me to post the link where you can hear this coming out of her own mouth?
No, what I'm saying is what if she truly didn't think the calls could be made. You're only looking at it from the perspective that DB made those calls. I'm not saying she didn't but that's not a 100% certainty, is it?
