Or call for a fake SWAT raid to the same house, so that the owner is either being shot or imprisoned. If that can really be triggered from distance without breaking in, it would make it the perfect revenge weapon.
I surely don't want to swat anyone. My concern is that someone with the right technology might use (1) this vulnerability to call a raid to an "enemy" from its own assistant without breaking in or leaving digital traces: no fingerprints, no malware installed, essentially no smoking gun, therefore creating a scenario in which the home owner might either be shot during the raid or prosecuted for calling a false alarm.
My point is, you can swat someone by just calling the police pretending to be someone else. That's how everyone is doing it already. No need to do it from within the home.
