That laser microphone tech is a decade old at least.
What they can do know is use radio waves and radio telescopes similar to those that SETI That searches for life in distant galaxies.
They discovered that those radio mics are so sensitive it can pick up the vibrations of the fabric of your clothes when you speak.
It started in the 40’s with project tempest van eck phreaking ect.

Most sensitive locations use vibration generators on all exposed exterior surfaces that could be monitored for vibrational patterns (speech). Glass pane recorders were ubiquitous in spookdom in the 1960s. Soon, oscillating vibration generators and multiple pane dampeners were in use.
Now, technology has been developed to pick out speech frequencies from among the generated frequencies and then map a complete conversation. Limiting factor, for now, is distance. Sensitivity is at the cockroach-scurry level.
I knew the laser bug technology had been around a while but figured by now they have it down to a fine art and/or distributed to every podunk cop in the country.
