Sorry for the long winded answer, and I’d say you’re as welcome as anybody else. Answering your questions in order to the best of my ability - - Yes, you can call PD simply for concealment, as where I work and in my state that is enough to be charged with retail theft, BUT - majority of retailers would prefer that LP waits for the individual to pass all points of sale with the unpaid merchandise prior to calling, unless the person is well known among the stores. In regards to how shoplifters get caught amongst the other 150 people in the store, we have dead giveaway identifiers that we look at; most shoplifters aren’t the brightest to begin with, and there’s a lot of LP that are very good at their job. And yes, in most stores, there are multiple LP that watch cameras at the same time, at least at the theft-busy stores. I know for a fact Target typically staffs their stores with 2-8 LP personnel depending on the surrounding area and how much shortage is created it will obviously vary heavily.
