1. A method for incapacitating an object using a non-lethal projectile, wherein the non-lethal projectile includes a control unit attached to a motion sensing device and an incapacitation mechanism, the method comprising the steps of: firing the non-lethal projectile at the object; upon the non-lethal projectile attaching to the object, sensing motion of the object by the motion sensing device; and deciding whether to provide an incapacitating stimulus to the object or not to provide said incapacitating stimulus based on the motion sensed as meeting at least one criterion, wherein said deciding is performed by the control unit, and said incapacitation stimulus is provided by the incapacitation mechanism.
