This tech does more harm than good when dealing with professional killers (governments). This type of audio triangulation is easily defeated, primarily because of how weak the signal detected is (audio, even from a 170 dBm source, is very low energy 1km away). With a single phase array emitter directed at the detectors, you can simulate a gunshot anywhere you want with less than 1 watt output. Such devices have already been built (by both Israel and Germany) to defeat this technology, which has been deployed near battlefields for a lot longer than in cities.

I was under the impression that the whole idea of a laser trap is that you CAN'T drop the ball. Small particles get trapped in the beam due to photon pressure, if the particle shifts away from the center of the beam, it automatically is recentered. Then you can move the beam to manipulate the particle which is attached to a molecule. They use these to fold and unfold proteins, lipid layers, DNA, etc.

I mean, it's great that they're using a realtime kernel, but they really shouldn't NEED it.
