With the onset of huge data centers there is no dearth for storage and unlike IPv4, IPv6 can be used to assign IP address to any device on planet earth.

Internet of Things, what wiki says about IoT
"The Internet of Things (IoT) is the interconnection of uniquely identifiable
embedded computing devices within the existing Internet infrastructure.
Typically, IoT is expected to offer advanced connectivity of devices, systems
and services that goes beyond machine-to-machine communications (M2M)
and covers a variety of protocols, domains, and applications."
IP Address and Camera
Why should a citizen of any country maintain secrecy of holding licensed Revolver.
Now a days every phone/tab has two cameras, say, front Camera and back camera.
Lets apply same concept for gun/revolver, whenever someone fires a bullet it should take photograph of person who fired the bullet and the target where bullet was fired at. Upload the taken photographs immediately to the Data Center.
Apart from Photographs we can save other information like
Make/model of Gun/Revolver
Make/model of the Bullet
If someone tried to modify the firmware on the Gun, it should send an Event to Data Center, so wa know something malicious is happening.
Why will terrorist buy a gun with Camera?
Nation states/Governments should make it mandatory for every Gun/Revolver manufacturer should have an inbuilt Camera and an IP Address.
