I work with computers all day long and I'm quite proficient and fast on them...for what I have to do with it on a daily basis. I have no freakin' clue about what's going on inside the box, the network or how the programs were designed. I'm an excellent driver....but I couldn't tell you what's really going on under the hood of my car if I had to. Most police officers are the same about their cruisers. They also probably couldn't explain, from a medical standpoint, how pepper spray and stun guns effect the body and do what they do.
I'm friends with a few police officers, and when it comes to shooting their weapons and the tactics used...they're great and know what exactly what to do.
