We are our own worst enemy when it comes to being prepared. We all know officers who are very tactical and many make fun of them, saying they're being paranoid. I remember going to alarm calls and responding as if someone were still inside. My backup officers would just walk up to the glass doors and tell me to calm down because it was probably just another false alarm. Why criticize officers for taking officer safety seriously on the job?
Another example is the Columbine High School shooting, which changed how law enforcement dealt with active shooters. No one questions a go-bag anymore, carrying a rifle, or conducting training in small unit tactics. Prior to Columbine, however, doing such things would have been deemed unnecessary, or considered overreacting by your command staff, or pegged you as a SWAT wannabe.
Being prepared means you are ready to face a zombie attack by staying in shape, maintaining proficiency in the tools of your trade, participating in as much relevant training as possible, and in committing to your agency's mission. On the flipside, being paranoid means you think zombies exist and have already infiltrated all levels of government.
If we feed into our fears, being paranoid is problematic at best and tragic at its worst. Though I am using paranoia loosely to make a point, real paranoia is a thought process believed to be heavily influenced by anxiety or fear, often to the point of delusion and irrationality. Paranoid thinking typically includes beliefs of conspiracy concerning a perceived threat. It's not a stretch to think that everyone is out to get you, because it sure feels that way at times. Regardless of what you are calling it, supervisors need to focus on calming fears that thrust officers into artificially induced hyper-vigilance and clouded judgment.
Being prepared means being ready to face the challenges thrown at you while you work. You must train to meet those challenges. What's important to stress is the application of core principles. Since no two situations are ever the same, understanding the principles gives you the widest possible range of tactics. If you pay attention, the situation will always guide you as to what tactics to use.
