This seems almost dishonest real unfamiliar with the subject in how it’s presented. The immediacy of the attention you get is really important: A gunshot can be heard for over a kilometer in any direction, even through walls. A laser pointer is both much less noticible and much less dangerous to bystanders.

edit: wow, I phrased that like an asshole, sorry.

You’d be better off calling in a drone strike. Capable of hitting the target from beyond visual range (over the horizon) with a low risk of missing due to the explosive payload, and zero chance of being heard or seen by any camera in the area.

Sarcasm aside, a gun is loud enough to cause permanent hearing damage to those around you, and the bullet will over penetrate the camera, continue to fly, and possibly hit someone downrange of the camera. Especially since cameras like that are obviously located in high traffic areas with a large number of people passing through. So under ideal conditions where you hit your target, odds are good that you will also hit a person. And in the event that you miss? Well, you most likely just shot someone. Isaac Newton is the meanest son of a bitch in space for a reason and 9mm is the preferred pistol round for the police and military because its generally larger size and smaller powder charge compared to other rounds means that it has a lower velocity and is therefore less likely to pass through a target and the wall behind them and hit somebody in an adjacent room.
