I don’t even think an airgun could really have an effect, but for anyone contemplating this kind of thing, please at least deconstruct the device and put it into something different looking. There is no point in getting offed with impunity by some Idiocracy goon because he saw a finger gun.
Better use of one’s efforts could be to support legal challenges of this clearly unconstitutional mass surveillance by the government through its corporate, or in this case, YC cutouts.
There are airguns available otc with the power equal to roughly a 45 ACP fired from a pistol. I doubt these cameras can resist that.
