For example, you have a home security system that you monitor from your mobile device. Perhaps you have your pet at home, there have been break-ins in your neighborhood, and just after someone showed up on your doorstep the CCTV feed cuts. You are not at home and the cops are busy. - But you have the skills to defend your home's electronic presence. You suspect a life, your pet, may be in danger so you have a good motive.
What then?
There are some places that allow defending a home using automation using non lethal force but even that comes with some risk of civil legal issues. This is why I suggest consulting with a lawyer. Even with non lethal means one would want to ensure it is legal in their location and that they have the proper signs with appropriate verbiage and mitigating controls in place first. Also understanding what laws are enforced and how they are enforced in your particular area is useful. My own personal solution was to move to a location that supports your idea and the Sheriff would likely high-five me if I take out the trash. There are trade-offs of course and hopefully such things are never required.
There was talk at one point of creating laws that supported counter-hacking but those never happened and it is highly unlikely they would ever pass. Proper attribution is hard enough. There are endless rabbit holes of problems such laws would create. At a minimum there would be a vastly increased requirement on everyone's part to increase audit trails and data storage alone would become a booming business, far more than it already is.
You can defend your home with lethal force in many states in the US. No verbiage, signs or disclaimers required.
