Well yes, but if you're not skilled enough to use non-lethal force to restrain somebody, then you really shouldn't be trying. If only from the point of looking out for yourself, because if you aren't sure of your ability, then you can't be sure you'll be able to overpower them. Add to that, if they are no longer a threat to you, you don't have the right to kill them. You just shouldn't go after someone unless you are sure you can do so safely.
