So, what I have always called, "shopping". Very few stores, do I feel comfortable with loitering. (one damaged freight, can have any and everything type of store, that is pretty much it)
As to what does security mean to me, well it is an illusionary emotion/belief. In the way people feel they know Christ/God/the flying spaghetti monster. That sense, provides a calming function, while helping one make more long term thoughts, then fear and paranoia do.
I've been abducted, hung around a serial killer, been at gunpoint five times, knife-point once, had both a car and house broken into, dealt with different criminals (murder/rape/thiefs, etc), had stuff stolen, been involved in an ugly lawsuit that nearly made me homeless ($500 an hour lawyers, were the inexpensive ones), and lived on $8k one year when I had to have a surgery and recover from it before being able to go back to work. I am on the low income side of things. Those I know, or are two degree's or less from me, on the opposite end, have their own security issues. Security is a state of mind, not an actual thing. Someone wants you, or your stuff, they can find a way.
