Remember that you are at a disadvantage when trying to take someone into custody. You cannot use all the tech. you have if you are following a force matrix. You must wait for them which gives them the upper hand. Better safe than sorry. ALWAYS immobilize them in some manner. It doesn't have to hurt them or be brutal, but make sure you are in contol. Don't let them see the cuffs. Many get nervous and you can provoke them by letting them see the cuffs. Always approach from their blind side if possible. If they are on thier knees, have them cross thier ankles and gently step on thier ankles while cuffing if you can. If they try to get up, step harder. And finally, try to keep the key hole up so you can unhook them or switch custody easily.
DON'T EVER PUT YOUR HANDS ON THE CHAIN. SOME EXPERIENCED HOODS CAN BREAK YOUR HANDS AND FINGERS.
