Why does TV get more leeway?

I know more than a dozen people in law enforcement.
That's not odd as I was on a first aid squad for 18 years.  We interact with the cops on a regular basis. When you call 911, depending on where you are, a police officer responds first.
Of those people in law enforcement half of them are or have been directly involved in investigating crimes.
In other words I have some great resources.
And none of them watch any crime shows on TV. They wish their jobs were that easy.
So I know from my research that crimes don't get solved in a half an hour and that crime scene techs wear, at the very least, booties on their feet. And that sometimes Emergency Medical Services has been there so the crime scene is not pristine.
But there are more than a dozen crime shows on TV.
If I wrote a book with that many inaccuracies, NO publisher would buy it.
Is the TV watching public not so smart? Being someone who watches TV, I'd like to think they aren't.
But publishers and I assume book buyers will not put up with such things wrong in my story.
Why does TV get so much leeway? Anyone have an answer?
