I'd like to know three simple things...
3) "Walker" suggests earlier that in would take a professional or organized crime member to pull of something like that... Even a cop who knows the maps of security cameras in his backyard or all of Bloomington, let alone a college kid would be able to pull of some ninja like performance and make a 20 year old girl just straight up disappear and not show up on camera...
What I meant was specifically inside the bar. Say CR's drink was spiked, maybe LS's, too. Or maybe she drank some of his drink. To then rob them would take knowing how to avoid the bar cameras (and some places have quite a lot) at least at crucial moments and also how to avoid making a scene in public. They would need to use the right drug to incapacitate CR but not cause him or LS to have an immediate medical crisis, which would have attracted attention. Robbing them inside the bar would take skill and planning. Just knowing that CR may have been carrying a lot of cash would have taken serious surveillance. That's why I say that they would have to be professionals.
