Unfortunately, training time is often apportioned based on perceived liability. Departments get sued when cops shoot someone, or when they beat someone up, or when they crash while driving somewhere. They seldom get sued over what a cop says -- even if those words led to the cop having to shoot someone.Here's one I've never been able to understand...
A professional cop - one who takes his job seriously - realizes that he can't take on the world. Fights will come to him whether he wants them or not. One lucky punch in any one of those encounters could have him in a wooden overcoat. Most officers never fire their sidearms except on the range. Many never point it at another human being.
And his job isn't kicking tail. A huge part is gathering information, keeping in touch with everyone from informants to citizens to the people he arrests. And when he talks he has to make sure people understand what he's telling them and get them to do what he tells them to. Lord knows those can be harder than the inside of a banker's heart.
A cop uses his gun almost never, his baton once in a while, his hands quite a bit and his communications skills all the time. So why do Academies spend lots of time on shooting, some on baton, a bit on unarmed defensive tactics and just a smidgen on communicating? It all seems a bit upside down.
Additionally, there's been an attitude that we all learn to communicate effectively through life, so it doesn't need to be taught. As someone who had to learn the hard way about communication... I know different. We're only just recognizing it, outside of "special communication" like interview/interrogation and Verbal Judo.
