So in reply to the posters who said I could still have used a phone: I could not. I had an Apple iPhone of exactly the kind covered in the class-action lawsuit, of which there was one in Chile, and I was eligible for the payout, still am in fact, it's like 170 dollars. But I haven't.
So I left that one at home, and in fact one of the people who came grilled me over and over as we walked down Victoria Subercaseaux "why didn't you bring your phone?" "WHY DIDN'T YOU BRING YOUR PHONE?"
Well I told him I had a similar phone, just no radio, and was connecting to the Walmart subsidiary's wifi with it, explicitly ordering the guards for the password after the cashier, CE NEWEN according to the receipt, made her premeditated apology. But surprise, screaming worked. It actually worked better! It was much better for someone else to call on my behalf than for me to call myself. And secondly, too predictable, they can tear the phone out of your hands, these guards were in gang-up beating mode, so they would not have tolerated a phone, the obvious choice. Very impatient and there were six of them, apparently armed.
When I got home and received a call, the phone I was supposed to take, its battery died. So battery would have died calling people on my own behalf, when the battery dies unexpectedly, the battery meter acts weird, it's not like getting locked out, when it dies it's a brick, you can't call emergency services.
I couldn't slowly put anything on the ground, these guards were in Fuck the Law mode. Evidently, because they never had any interest in my receipt, or my testimony. Six, 6 guards, shepherding me coercively back to the Walmart subsidiary where they controlled all the cameras and knew the terrain, could make up any shit they wanted. And a lawyer that came, called Nacho, told me exactly that, these guys don't like calling police because they want that power for themselves.
The uniforms say SWAT on them, S-W-A-T, supposedly it's SWAT-branded private security apparel, nothing to do with American Special Weapons And Tactics like in the movies. Like Apple computer having nothing to do with apples, just a brandname, "nombre de fantasía", it's not like actual fruit. So they're trying to intimidate people with the power of the law, precisely so people don't dare defend themselves, to imply their victim will get accused resisting arrest.
