Does it matter what the plaintiff thinks, if the guy wasn't working as a real officer? (Which I tend to think, but don't know he was. I'm open to being told he wasn't but with how little we know, I lean towards LEO [for the sake of argument right now anyway] with all the accouterments he had car, uniform, etc.)
If some guy dresses up as a cop, paints up a motorcycle, steals/fakes a ticket book etc. starts pulling over high value cars to get their address, and possibly copy their keys through con artistry- turn off your vehicle, step out of the car, manipulate their key in an impression maker while they're taking a field sobriety test, or whatever. I hope that was ridiculous and specific enough to obviously not supposed to be a real person or situation- I don't think anyone here thinks those drivers/victims should be able to sue the local PD because they thought the guy pulling them over was a LEO.
Either he was an active LEO or he wasn't. All the government property he had with him certainly suggests, but (probably) doesn't definitively prove he was during his actions, an active LEO.
And Spats, maybe you can chime in on my devil's advocate question after saying all of that-
Can an off-duty officer go back on duty in an emergency situation? I.e. can an off-the-clock patrol officer go back on the clock if he walks past some guy beating the crap out of his kid in the front yard? Stop the beating, arrest the guy, call for a car to come pick the guy up, and take him to jail/booking/etc?
While it's fairly obvious a private security guard could seize a person, can/do they search that person? Or do they wait until the police arrive, let the police do the search incident to lawful arrest to maintain chain of custody for any evidence found?
If so- Assuming he wasn't being paid by NO PD, which was being paid by Whole Foods- would he have gone back "on the clock" with any of the actions he's alleged to have committed?
The level of "violence" or method of it's application in the encounter?
The search of his person, including the securing and emptying of the firearm?
Seizing a person the store itself did not have the right to seize as no shoplifting was alleged - As I understand it the store only had the right to ask/tell him to leave, not hold him in a back room to lecture him, take his property, manipulate and empty it, then slam it on a car hood outside the store property?
And now that I type that out, I think that's the key point isn't it? Who decided what would be done in this situation. If the store manager ordered the detainment, then it's more likely the store. If the officer/security guard did it on their own volition and either appropriated or extended his access to that back room and who he could take there, it could have been acting as a duly sworn officer.
