Security technologies are spreading more and more. Some of them, such as the security robot K5, guarantee and destroy security at the same time. Mass shootings such as those in Dayton and El Paso are a particular problem. New tech firms like Athena are offering solutions, as Fast Company reports. “Athena Security uses object-motion detection to spot when an individual brandishes a fireman, and immediately send an alert to their client, whether that’s a private security firm or local law enforcement. The company’s AI object-motion detection is camera agnostic, meaning it can work on any CCTV system. When a gun is detected, the video feed of the active shooter is made available to the client both on mobile devices and desktop computers, allowing officers to know what they are dealing with and where it is happening, all in the space of three seconds …” (Fast Company, 23 August 2019) In fact, technologies are often the only means against technologies. They may also be successful in preventing mass shootings. Another possibility would be to disarm the population – but this would meet with resistance in the USA. Another problem is that this is surveillance technology. Therefore, as with the K5 and other service robots, one thing applies: one form of security is gained, another form of security is lost.
