What Is Theft-Aggregated? I have been searching for information on this topic for hours and I can't get any information on it.

Can a man of age of 20 go to jail for having sexual intercourse with a girl of the age of 16?

My 17 year old son was arrested for underage consumption of beer. He was never read his rights when they took him to the station in their patrol car. Does that matter? He told me this as soon as I picked him up that night.

Can a general manager open US Mail that is addressed to an employee?

My son's were found in the parking lot of an abandoned warehouse as they were rounding the corner of the building from the rear to the front. They were intercepted by three police officers. The police officers not only had their weapons drawn but immediately pointed them at my children, ages 16 and 12 upon which time they ordered them to freeze. They then ordered them to the ground; my eldest was a little faster however, my youngest was obviously not acting rapidly enough and after getting to his knees was helped the rest of the way to the ground by the foot of one of the officers. They were immediately handcuffed, patted down and placed in the rear of a cruiser. The officers then told them they were under arrest for burglary and vandalism. My questions are as follows: 1. Since they were found outside of the building and there was no proof that they had been in the building, does this not constitute more of a trespass charge. 2. Since they were never asked if they had entered the building, is it not presumed that they are innocent until proven guilty? 3. What constitutes excessive force and what actions are acceptable for police officers to exhibit?
