I prefer to shoot them in the legs if theyre already prone on the ground,
if theyre not, morphine is a good thing (make sure you have a medic around then)
As mentioned before, AFK guys have to go in vehicles isnt a thing...
There were some situations on the public where i wished the afk guys werent in the vehicles because there is a high chance that the vehicle gets blown up than..
i dont know if its possible to script but something like: afk > 5m auto handcuffed, person comes back (ie: moves mouse) handcuffs off
