Vegas Strip

I watched a couple of episodes late at night when I had nothing to do. As I lived in las Vegas some 20 years ago, it was of passing interest. However, I was horrified to see the actions of the police who seemed to be very suspicious and aggressive. One 'veteran' cop called upon a guy to stop and when he didn't he was tackled around the neck from behind and handcuffed. He could easily have been deaf or, with the street noise, not heard the officer call out. At this point that was his only 'crime' - not 'doing what he was told'. Another guy was arrested for 'suspicious running'. This is police work at its worst. If it were possible arrest a guy for resisting arrest, these cops would do it. This was taking probable cause to the extreme. 'Hey that guy is not acting normally - let's arrest him' - the guy was celebrating his 21st birthday and had been drinking. A walking crime wave no doubt. This series seems to be similar to other 'cop reality' programs where people are arrested and assaulted for traffic offences. The fictional TV shows are worse. An address is found for a suspect that detectives want to talk to so they go there with a fully armed SWAT team, with snipers prepared to shoot anything that moves. Is this the reality of the police in America?
