The next step should be filing an ethics complaint with the PA bar association against the DA for the bogus charges. (obviously bogus because of the late filing) Think Nifong.
I'm not sure how to say this; the cop is lucky that it wasn't a trap. [I started to go into details and then changed my mind. Don't want to give anyone ideas.]I don't get it; if he had a CC permit then why not keep the weapon out of sight? That said; the cop only felt like he was in danger, because he drew down, from behind, on a dude who was just minding his own business. I guess some cops only feel comfortable doing their jobs if they are the only ones carrying. If I was the cop, I would be looking for a new line of work.
