Never said, nor implied any such thing. Basic laws against nuisances and noise, especially after dark, are very similar from city to city and State to State. I highly doubt that a big city such as Houstin has any less restrictive laws than say Jacksonville, Tallahassee or Pensacola here in Florida. Such gatherings, in unenclosed, undesignated areas are not allowed after dark. The cut-off is usually 9pm, but it may be slightly later from place to place.
But again, you do not even want to hear this. You just want to call me names(something I haven't done to you) and talk about how I'm a tyrant, a police state advocate and whatnot. I agree with you mostly about the arrests being wrong. What I wil not agree with you, and will not back down from, is my opinion that the people 1)Were doing something dangerous, and something they knew they were not supposed to do and b)that the cops had every right to disperse the crowd, regardless of "owners permission". Again, I work day in and day out with real estate and legal issues concerning it. I know such issues as noise and nuisance are addressed in every planning/zoning code and such gatherings are not permitted in such places as K-Mart parkings lots after dark. Its a frikin mixed-use area which includes residences. If a resident can hear the crowd, its not allowed. K-Mart would need a specific permit to have such a gathering, and it would not be allowed in the wee hours of the morning. If you do not believe this, then I am sorry. I will waste no more of my time trying to convince you that this type of behavior is not allowed, whether the property owner wants it or not.
