I just want to add this to the discussion as well. From 2017, it is an adversarial 3d printed turtle that some recognizers detect as a gun: https://www.theverge.com/2017/11/2/16597276/google-ai-image-attacks-adversarial-turtle-rifle-3d-printed https://www.theverge.com/2017/11/2/16597276/google-ai-image-... Its dark, but I can envision someone giving a version of this bad boy to someone they would like to prank. Kids will be kids... There is no need for this razzle-dazzle anyhow. The more ethical solution is to add a beacon to the id card or bracelet or whatever you need to move around the school, like an EZ-Pass. You can use a shielding bag or turn them off or leave them at home when you aren't at school. You can use human presence sensors to identify people in general and where they aren't. When theres another tragic shooting, you can failsafe open the maglocks or access controls except where people are taking shelter, and either track the person directly or track where there is a person without a beacon. Then, give cops the regular camera feed for situational awareness.
