The friend of one of my relatives recently had her house broken into and robbed in Everret MA. The thieves entered by pushing in the window located air-conditioner, then climbed through the resulting void created when the device fell inside on the floor. Yes it made a racket, but they were in and out very quickly, grabbing several items.

If only the owner had purchased an air-conditioner with a Claymore Option. Had they done so, pushing against the device from the outside would have activated the compressed gas powered outer grill. This would have then explosively flung the potential miscreants backwards to where they came from.

In the delux version, the gas would also have rendered them unconscious until the police arrived, summoned by an automatic call to the local constabulary sent by the device's activation.

You can opt for the lethal semtex configuration. (totally illegal of course)

Easier option: snare hidden around the air-con in the wall. So they get halfway in, then they're gripped around the middle and have to wait for the police to arrive.

Is built-in air-conditioning not a Thing in the USA? I don't think I've ever seen a "window mounted" unit here in New Zealand.

[neutrinos_shadow], built-in A/C exists in USA but not in every building. Window units are a common retrofit.
