In a very near future scenario, a society developed high flying drones equipped with cameras. Together with satellite surveillance, law enforcement can check whether citizens behave in accordance with the law. This functions in a manner similar to modern surveillance drones utilized by some armies and private companies today. The addition is an AI to coordinate and control them in an optimized manner.
The drone program has been well received by society. People are happy with the rapid intervention of the police, and streamlining/speed up of investigations.
Leadership now wants to take the next step and replace on the street law-enforcement officers with drones.
- The technology is very promising, and the first field-tests are pretty conclusive.
- Unfortunately, the polls show me that people aren't ready to give the right to harm or kill to machines.
- In response, a trial period will be held, were traditional weapons are replaced with something non-lethal.
That new system should be along the lines of
- It should be installed on the flying drones controlled by a central AI;
- It should "attack" the persons who would have been judged (by the AI) as being a danger to the others (like Police would be shooting, to harm or to kill) and/or to the surveillance or enforcement drones themselves;
- It should "tag" that person, so that the police can effectively identify on the spot who was responsible for the problems.
One idea that engineers have floated is using paint balls. However due to accuracy problems, the tactics of the drones have to change, requiring they get closer to their intended targets. Additionally paint balls may result in injury, which leadership would like to avoid at all cost, to maintain a positive public perception.
To convince the population, I want something that is as harmless as possible. Ideally it should simulate a real weapon, mark the victim, and preferably do so without making the victim aware they have been tagged.
