Old Town clubs, glad I out grew the club scene, especially there.
Most of Olde Town is within 1000ft of Brock Elementary, St Tammany Jr, or Pathways School. Back in the day, the cops often charged drug dealers of possession within 1000ft of a school if they catch you inside
one of the bars with dope. (ie The Balcony or Catz).
By my measurement, Its 850 ft from the door of Heidlberg's to the entrance of Brock.
It's 990 ft from the front door of Club Pheonix to the entrance of Brock.
The entrance to Old Town Tavern (formerly Minicapelli's) or the Old Town Soda Shop is outside the 1000' GFSZ of Brock, but might put you within 1000ft of Pathways.
Best suggestion: Stay out of OT with your guns or dope!
I agree with what most folks have already advised you.... get a lawyer (preferably weeks ago), stop posting here about the incident (save your arguments for the courtroom), write everything down (preferably immediately after such an incident), and give your account of the incident to your lawyer ONLY.
One thing I can add is that, it sounded like the cops never actually saw you with the gun out of your vehicle ( BTW there is no OC in the hand, that called "brandishing"), so someone else (an unnamed witness) advised the cops of it, then they had PC to search your vehicle. A good lawyer might can argue out of that one, but IDK.
Also, the disturbing the peace for fighting charge is tough to beat in court, it's your word against the cops. in 1999 the cops arrest the bouncer at Minicapeli's for "DTP by fighting" when he was breaking up a fight between drunks inside his own bar
I'm really sorry for you to hear about this, if that is any consolation. Unfortunately, I think you are pretty much screwed.
