Compare this activity in other countries
This makes the rule page useful for comparison without creating a second data source.
Australia
Australia does not have one uniform civilian stun-gun rule. Victoria Police classifies a Taser or stun gun as a prohibited weapon, and Victoria Police approval material says prohibited weapons generally require Chief Commissioner approval or an applicable exemption for purchase, possession, carriage or transport. Australian Border Force customs material treats handheld electric-shock devices, including Tasers, stun guns and stun batons, as arms.
Belgium
Belgian Justice lists portable devices that use electric shocks to neutralise persons as prohibited weapons. Prohibited weapons cannot lawfully be possessed, bought, transported or carried by civilians.
Canada
Carrying a compact stun gun is not lawful in Canada for the public because the device is treated as a prohibited weapon.
Colombia
Colombia authorizes electric less-lethal devices only within the framework of Decreto 1563 de 2022. Electric devices are only authorized if they meet the decree’s technical specifications, and the civilian possession and carry framework requires marking and a permit process for less-lethal items.

Why the page is intentionally light
The new site should show a stable layout, a stable route, and clear source slots before the dataset is scaled up again. That keeps management simple and makes later official-source population safer.
