You being killed by a criminal over an iPhone or laptop is not going to change anything. Fund your police, vote to change laws enough that they’re spending their time on things that are relevant, and if you’re honestly willing to die for the rule of law, become a police officer.
Otherwise your body will be one more on the list of “people that died for no reason.” It’s not tough, righteous, or whatever else to die for no reason - and even if it were, if you’re going to make a stand and sacrifice your life, make it over something more than a laptop.
