That part doesn't really strike me as odd. A suburban dumpy old dive bar not having security cameras in 2012 would have been pretty normal and unsurprising, as would a local suburban cop doing a piss-poor job of clearly writing that on a report. Hell, I know of a LOT of places in Providence that didn't even have cameras 10 years ago.

Plus, at the time, there's no real reason to suspect anyone specific, much less a state trooper.
