It's a pain-compliance device. Just about the oldest and simplest to stop someone doing something, is to hurt them, that simple. Just like a truncheon, CS or hands and feet. Taser is the same principle mixed with modern technology to allow extra range. The absolute vast majority of people these weapons are used against by police wouldn't hesitate to kill or hurt a civilian or police officer to get away and the vast majority survive with the most minor of injuries.
They are LESS LETHAL not non lethal. In Britain for example they are a lot less lethal than a police marksman with an assault rifle(the alternative). I don't really see how the fact they can and sometimes do kill people is an argument against them. Any more than it is an argument against ASP's and fist's. Which every British copper carries and also kill people.
Don't want to get tased? Simple, do what the officer tells you, or y'know, don't break the law in the first place. In every western country I can think you'll get ample warning before one is used and multiple opportunities to surrender/comply.
It's a choice between a burst of 5.56 to the chest and certain death or 30 seconds of pain and a tiny chance of death.
It's not 'safe', it's safer. It's a stepping stone between non-lethal and shoot to kill in my mind. A sensible one to have at that.
Although I get the impression from some posters and from various other debates along similar lines in other places that many believe the police should be completely unarmed and more worried about sensitivity and diversity than being a robust force for dealing with the most dangerous and violent elements of society.
Is it torture? Well I've been tasered, it hurts like hell, yes, though not as much as some make out
IMHO and as soon as the trigger is released the pain stops almost instantly, unlike CS or a physical blow, I think the fear and shock generated by the crackling of electricity and loss of motor control causes most of the screaming and thrashing. The pain itself can easily be fought through. It's the incapacitation of the muscles that actually stops you.
In my opinion it's not torture, it's not pleasant, no doubt about that but I think anyone who would call it torture either; hasn't been tasered, is being over-dramatic for their own benefit or has lead a very sheltered life up until the point they met the nice officer.
Given the choice of getting doused in CS, beaten with a stick or a taser, I'd take the taser.
