Honestly, I think this is a good question. :) I think its because of what @Tyto says, sex sells. People have changed these days. People also think that police officers are the bad guys, and that they only want to harm us or something like that. But honestly thats not true. Nothing is free these days but people don't care, they'd rather be watching something about Miley Cyrus' life then wondering if they are actually safe.
