Welcome back, Karl!
Some final words about all of these techniques.
1. If going up against the police or other agents, would be to use the officers own handcuffs or flexi-cuffs (basically large zip ties) to restrain the officer during the precious few seconds they are incapacitated.
3. Simply have the character apply the technique, safely guide the target to the ground and use those seconds to run away. If there are additional pursuers, would the character want to waste time handcuffing the officer while other officers/agents are closing in on him?
Another thing to consider is, how would other officers/agents respond to witnessing the main character apply these techniques to one of their fellow officers? The answer to that question is it raises the stake . . . a lot.
