Whoa, I've watched this movie before in many neighborhoods. The 'taxpayers' vs. the no-good musicians. Ralph can ask for $300,000 but can't bother to buy a $179 noise meter from Radio Shack? How can criminality be proven with no evidence but hearsay. Sounds like discrimination to me. I will try to get by to at least sign the petition.
A simple suggestion; take up donations to buy a meter. I know times are hard, but this inexpensive devise can prove innocence...and NEVER resist or even raise your voice to a police officer. They have jobs to do and citizens to serve. They will always take the easiest way out of a tense situation and let the courts sort out things later. But with proof of compliance and cooperation with authority, you will always prevail.
Also. I have been a live sound guy for over 30 years as well. If I can be of any assistance to anyone, let me know. If I don't have to pay a cover to see you, the initial advice is free...and so are emails...always.
