Well, by comparison, taser guns are known to sometimes kill humans when they were meant to only stun...
I haven't actually tried the electro laser myself yet, I've been a bit busy recently and haven't actually played very far into the game beyond quick tests for some time.
Tasers (esp in a Playstation game - cant rmbr the name, i try to get me names after i made it home later), can kill. Medically, i have been interested in this, and read many medical reports on this online.
For those who are well, not so into this,
howstuffworks got something simpler here.
In summary, its something to do with electrical signals to heart being disrupted. Think of it as delivery an AED shock to a living person, the heart goes into fibrillation if not MI (Mayocardiac infarction) immediately.
But for gameplay sake, i thnk they should be stunning instead of killing rite? lol.
PS: What do u need to research to get that aniwae? I haven done proper gameplay for a long time. lol. Been trying out the maps on skirmish instead...... My 'new' game tat was started hardly got off the first encounter even. lol. Been mad @ work, and at celebrating with frds my bday. lol.
