Sounds to me like these are the newest revenue tickets. In Houston the fine for noise violations (at bars as well as private parties) has been doubled and there is no longer any decibel measurement. The police don’t even need to receive a complaint or enter the establishment to write a citation.
It’s clear to me, that a lot of people here are theorizing about imagined rights violations and have never been victimized by one of these exercises in freedom, on their block! The lack of civility is remarkable!
