Today's weapons and ammunition choices are unparalleled, and it is incumbent upon you to do your training repetitions with your equipment, and maintain that equipment in good working order. Not long ago I was standing in a crowd and saw an officer who had obviously spent the day in the wind and dust, and I chuckled to myself how he had a couple of hours of cleaning up to do on everything from cuffs to magazines; been there, done that. But then it hit me … I wasn't wondering whether he would prep his gear or not; just looking at his demeanor and carriage told me there was no doubt about it; I was just in sympathy mode. This dedication to maintain our gear must be ingrained in us all.
Next, when in doubt, take your time. We have tons of manpower issues, and often we have a greatly reduced number of officers on the street on any given call. We have communications resources greater than ever before, so never hesitate to have a complainant recontacted, or stand off and use good old fashioned binoculars to gather intelligence before going directly to a scene. Remember, squealing tires and intense accelerations only announce your approach.
Use all your mental skills, such as crisis rehearsal (visualization), to refresh yourself daily on procedures and tactics. Reinforce your understanding about when to confront and when to disengage – a word we don't like to use, but a tactic that can save our lives when used properly. Practice tactical breathing regularly. In fact, download the free Tactical Breather app and then use it in critical situations like pursuits (it prevents tunnel vision) and building searches.
Make sure you are full of good habits and have mitigated your bad ones. Do you use your light effectively? Do you practice sound control when you need to, maintain reactionary gaps, and "watch the hands" at all times? How is your positioning on interviews and vehicles stops and searches, both objects and people? Do you search expecting to find something, then add one to that expectation when you do (the Rule of Plus One), or do you just search lackadaisically?
How about your frisking and cuffing techniques? Do you maintain control of a subject both verbally and physically, or are you expecting everyone to be a "yes" person? Are you mentally and physically able to respond in the event of sudden resistance or assault?
