I believe regular citizens have the same expectations as a cop, whether they are on duty or off.
The USSC has ruled the police have no duty to protect you. Neither do I but there is an expectation of protection.
Perhaps DAT will weigh in on this for us. DAT, what say you amigo?

How does the law define "expectations?" That's the part that has me befuddled. And which law? Where?
If you're speaking of state law in Texas, that's one thing. Maybe Texas has such a law of "expectations" of citizenry when they witness a crime in progress. Federal law is something else, and while I'm no attorney (DAT, where are you?), I think it's a very, very difficult point to cite.
Here's my take on why your supposition does not make sense. While common sense tells us that a perp busting caps and taking people out is a crime and the perp needs to be stopped, preferably permanently with two to center mass and one to the head, your average citizen isn't
trained on what the law is.
Therefore, from a legal perspective, that citizen cannot make a legal judgment as to what comprises legal and illegal activity, especially when it comes to using force to stop that activity.
A cop, on the other hand, has been trained, has taken an oath, and otherwise is
qualified to make those types of judgments. That's yet another reason why cops aren't really "off-duty" and are expected to carry 24/7.
Show me where I'm wrong.
