Cops TV Show- First Amendment Rights Violation

What exactly is probable cause for a police officer to detain you and search you, including your body cavities? Well, I always thought you had to be breaking a law or at least a traffic ordinance or the police had to see evidence with their own eyes. I guess not.

The following case is an actual, real life example of abuse of power. The actions of the police officer violated this U.S. citizens rights as guaranteed by the Constitution of the United States.

A police officer sees a person sitting in a vehicle at 2 o'clock am. The last time I checked, this wasn't against the law. The officer walks up to the "suspicious person", a white male who appears to be between 30 and 40 years old. The officer tells the man to keep his hands on steering wheel and asks why he is there sitting in his vehicle. In America, we have to explain to the police what we are doing, just because they want to know? The man answers the officer, saying he was waiting to talk to someone about a contract job. The officer doesn't like his answer, so he tells the guy to get out of the car and put his hands on the hood of the officer's car. The man complies, and the officer continues to question him about his reasons for being out so late. The officer asks the man to consent to a search, and the man gives permission. The officer believes that the man has an illegal substance in his mouth and requires (not requests) him to show the officer the inside of his mouth. Last time I checked, permission to search didn't include body cavities! The officer claims he sees "something white" in the man's mouth (Perhaps teeth?) and starts handcuffing him while reaching inside his mouth. Other police officers assist, reaching into the man's mouth and restricting his breathing. During this entire time, the man is never told he is in custody, under arrest, or has the right to an attorney or to remain silent.
