Au contraire, it's of huge significance.Its good to see that there is a general understanding that the phone call is of little, if of any use.
As Heri aptly explained, the log places the phone in the confines of PDL (not 35km away as some people seem to believe). Other masts would have picked up the call if it was further away.
The issue is with that is... CB claims he never went back to PDL after he was released from prison in 2006. So how was his phone there that night?
