One issue is that this a lot different than an aircraft carrier cannon. Those are super expensive and limited in where and how they can be used. Also, the bigger the fear is that we don't know where this will stop. Great, so drones are being used in war for strategic strikes. Given the current administration, how long before that might be used to track down people near the border? How long after that to track down people who publicly criticize the administration? The biggest issue is that this enables an Orwellian society that actually scales and scales quickly.

And for anyone playing at home, the "if not us, someone else" argument doesn't wash. We as a society have to draw a line. Maybe someone else will do it, but we need to fight them and not allow it, not just take our money and put our head in the sand. Just like the backlash about the NSA putting backdoors in routers and the more recent announcement of Amazon enabling a police state by scanning and identifying faces in pictures and videos. I'm worried that this will continue to push us to some pre-crime bullshit but instead of oracles with magic powers, it will be some half ass AI based on factors like race, gender, neighborhood and time of day.
