You can now understand why retired agent and lead salesman for ShotSpotter, David Chipman, had such a sense of doom and gloom regarding suppressors.
It isn't just that he leans to government confiscation and regulation of individual rights WRT to arms and accessories, but more important for him and his company, they would have to invest substantial time, effort, and resources into developing the sensors and software to attenuate to suppressed gunshot signatures.
After the past 2 years of their losses, they launched their IPO in June to help infuse cash. They lost $6.13 million in 2015, and $6.86 million in 2016.
Understanding those facts helps explain why Chipman had such a bleak and dire outlook on life as it relates to suppressors.
In reality, even the ATF's own senior leadership says they're open to reevaluating inclusion of suppressors on the NFA registry, because they just don't see a lot of issues with them, recommending prosecution only 44 times a year, where only 6 of the defendants on average have a prior felony conviction for some other crime. That seems to indicate prosecution recommendations for people who have manufactured a suppressor who otherwise are not felonious offenders until they cross the line and make a sound moderator.
