I was watching CBS news tonite and a story came on about a guy who was an airline pilot who was stalking people... so the PD found out so they got one of his calls on tape to they found out where the call was made (payphone) and it was on a calling card. They found out who bought the calling card by Tracking who bought it by finding out the member number on is member card at a sams club. (ok that was a bit confusing) point is face it people if the gov wants to track u they all ready can Most large stores have these stupid member cards now you can be tracked by looking what you buy you have a member number registered to you. I have never got these cards because i dont like them sending me shit in the mail now i have a new reason so the .gov cant see when I buy what. what a bunch of BS IMO
