The application will be over clothing and never on skin if possible. The biggest problem with application directly to the skin is removal. The body hair will be pulled, along with loose skin, scabs, or open wounds and the general discomfort of removal. If the clothes are loose fitting or baggy, you will need to gather the fabric up tight to get a good hold on the limbs. If the suspect has a plastic cast or a prosthetic device, it can be taped over these items. The tape will have to wrap around the torso if an arm or around the other leg if a leg. In addition there are two important points. First, avoid excessive movement of the limb due to its medical condition. Second, be extremely careful because a cast or mechanical arm could be a great weapon for a resisting subject.
A very important concern here is not to cut off circulation in the extremities. I always recommend medical attention for prisoners following a violent encounter. Because of the unknown levels of toxicity of unknown chemicals, injuries that were sustained before or during the encounter, and may not cause pain now due to intoxication. Monitoring afterwards requires evaluation by medical personnel. The trip to the emergency room is the best policy of all. It is far easier to treat a controlled suspect immediately, rather than wait for him to become a plaintiff.
In training you will have to train officers on how to check the pulse of either the foot or hand. To check the pulse in the hand, the officer will have to locate the radial pulse (thumb side) of the wrist. This will allow the officer to check for proper blood flow to the hands and prevent damage. For the feet, there are three pedis pulse sites: dorsal on top of the foot, medial on the inside and lateral on the outside. During training, instruct the officers on how to take a pulse from all four sites. It is important for them to check more than once when the suspect is restrained by tape. It is very important to document this action as well in a use of force report. If you are honest and articulate the circumstances, about suspects' actions, your actions, why you responded in the manner that you did, and follow-up, the humane side of the procedure will be recognized. Most important, remember what your FTO taught you "if it is not in the report, it did not happen." The secret to countering legal challenges or complaints is to be honest.
When to apply this technique will be defined by departmental directives (SOP's). I would further recommend that it be applied after receiving a field supervisor's approval. The wild kicking actions of a violently resisting suspect can be controlled by this method, but I would not recommend this for a drunk having a temper tantrum. Every agency has an officer that is problematic and we all know examples of this. It is for this reason I recommend that this requires an okay from a street commander. Otherwise, some officer may wrap someone up like a Christmas present.
These tactics require at least three officers to duct tape. Two officers will find the procedure difficult, if not impossible. In situations where there are two or more officers involved in immediate contact with the suspect, an additional officer will be the one to actually apply the tape. This officer is fresh to the conflict (not exhausted) and should give verbal direction to the other officers and provide cover from others that may be gathering. The supervisor should view this event and provide ongoing direction, requesting medical attention or special transport requests. How is the suspect placed in this position? In real world policing, somehow we often end up on the ground. If the subject is still on their feet, a takedown that you are confident with is suggested. Quick and decisive action is a must!
