Congratulations on not living in a nation that has caught the mass-murder-mania. b^)

It might not make economic sense yet, but the trend only goes one direction. Electronic devices get cheaper and more capable over time. Robocop might not ever make sense, because that is a very complicated use case. However, a constellation of devices charged with enforcing a single rule, "no human hands may hold a firearm in this set of rooms", is already nearly within reach of current technology.
