These guys wrote some ai / machine leaning type gun detection software:

Cool… however it’s kind of at the stage where it’s already too late if a gun is out in an active shooter type situation.  I suppose depending on the exact scenario it could provide some much needed warning to save lives.

The decision to not detect guns underneath clothing was a respectable one for numerous reasons, including not playing into the much perpetuated myth that everyone who isn’t law enforcement that carries a gun needs to be accounted for.

5:07 – Interesting how they trained it by pulling frames out of movies and other videos with guns being held in them.  Pretty standard as far as this type of thing goes, but it’s interesting to see it used in the realm of firearms.

Thoughts?  You completely ok with indoor and outdoor cameras, and other systems analyzing everything about you when you’re out in public?  I’m not, and it’s not because I don’t like safety, it’s because mass surveillance is nosy and intrusive.
