I was thinking of this group mostly in the concept of serial killers - they have lots of skills, the reason to travel and are usually alone for the whole day. Visiting populous towns would make them uncomfortable, but bars - they like, as alcohol works for social anxiety.
I have another question. What about these incessant stories, basically, in every case, about LE visiting local stores to ask it anyone bought knives, etc. I am thinking - what is the best place to shop for anything, local stores or Amazon with its huge bulk of sales? Maybe even Costco. I definitely would not purchase in a tiny store if I wanted to be forgotten. I don't know about Amazon's digital trail, but Costco is a good place.
