ELECTROSHOCK WEAPONS. (STUN GUNS; TASERS = NOT the SAME.)
snipped for focus.
@Dotta
(BTW, imo a person seriously deliberating killing another human, is not deterred by potential arrest or conviction for using an 'illegal weapon' to render a victim compliant before stabbing. But I have not yet researched legality of stun gun or taser posession or use in ID. May be legal there; IDK. )
BRIEFLY & oversimplified.
STUN GUN user deploys by putting device on/against a person & firing/pushing button. IOW, user must be at arms length to targeted vic or closer.
Civilian TASER holder can use it as far away from vic as 4.5 m (15 ft), because the device shoots two small, barbed darts at targeted vic, w each one remaining 'tethered' to the device. IOW Taser has longer range than stun gun, but user must have (some) skill in aiming.
W. either weapon, device typically becomes less effective thru thicker layers of clothing.
Tasers, waaaay pricier than stun guns. See amazon links below.

LONG TEDIOUS (boring) INFO re ELECTROSHOCK WEAPONS.
"An electroshock weapon is a less-lethal weapon that utilizes an electric shock to incapacitate a target by either temporarily disrupting voluntary muscle control and/or through pain compliance. There are several different types of electroshock weapons...."
"An electroshock is not a taser, though the two terms are often used interchangeably, stun guns and Tasers refer to two different devices. Stun guns administer an electric shock through direct contact, whereas a taser device administers the shock through thin flexible wires connected to two probes that are fired into the target.[1][2]

STUN GUNS.
"...A stun gun is any weapon that incapacitates its target without killing.[1] Tasers, tranquillizer guns, and mace (spray) are all types of stun guns. Subcategories of stun gun include the electroshock weapon, an incapacitating weapon that momentarily disables either a beast or a person with an electric shock; and a directed-energy weapon that causes unconsciousness, a weapon that emits energy in an aimed direction without a projectile...."

TASER (a brand name, but often used generically like Kleenex)
