The advantage of weapons is that they will not cause serious physical harm to criminals.
Taser makes the target temporarily "shocked" and lose the fighting ability, and will not kill the opponent, causing permanent physical trauma.
Effectively prevent manslaughter
Tasers won't kill the target, so the police won't kill people by mistake in the riot. Although the voltage of the taser's electric dart arrow is very high, the duration of the current is very short, and the current of 160 mA only lasts for a few microseconds.
