In most part of US, people have the right to protect their own personal property with an appropriate amount of force.With this concept of personal property and a persons right to protect as background, the scenario is:-
An intruder enters your home using the internet, then intrudes into your personal computer which is inside the home,steals data and decamps.
Can the property owner use any form of force to protect their property using violence ? Would such an attack be considered lawful ? ( You called 911 and the dispatcher thought that the call deserved a 51-50 psychiatric hold, while the intruder stole documents from your laptop and installed a ransomware)
How would you "defend" your property in this situation ? If you "attacked" the intruder, would it be deemed unlawful ?
