US tv shows?

What is it with US TV shows?  All the police series have glamorous detectives solving impossibly complicated crimes (nearly always a serial killer) with clever hi-tech crime busting.  Whereas the reality is a fat cop with an old computer hardly ever solving even the most basic robbery, and even when they do it's because the criminal is even dumber than the cop.

Then there's the "reality" shows, why is the boss always a hard nosed pretend tough guy (American chopper, sons of guns, battle machine bros deadliest catch etc etc etc) In reality an overweight bully with an attitude problem, who's showing off for the cameras.   And why is there always a dumb son or brother?
Do any of these people actually realise how stupid they really look?

Personally I cringe what I see some of the rubbish put out on channels like discovery, take Finding bigfoot (please take it away) every week a bunch of "squach" hunters go crashing through the woods with radios bleeping every 30 seconds, wondering why they cant find bigfoot.  Two reasons people, one because it doesn't exist, and two because even if it did exist the noise you jokers make would scare off anything within a five mile radius.
The way to find it ( if it was there)  would be to move in very quietly, and set up an OP covering the main tracks to any water, staying silent  (we call it hard routine) and wait for it to move around, you'll find bugger all thrashing about in the woods making stupid "squatch calls"  and talking constantly on the radio.
