If I'm correct, this happened around Aug. 25.
Sorry to hear about that, especially since "brief" exposure of a concealed handgun is suppose to be ok in Florida now. Keep your head up and lawyer up.
I think you might have found yourself as a test case for the meaning of "brief". I am not sure who to point you to, but there are many on here who can. In the mean time, I wouldn't give too many more details out until your attorney gives you the ok, if you can find one.
Also, your mugshot and arrest information is on bustedmugshots.com., and a "snapshot" of data on your booking by Miami-Dade County is located on jailbase.com. I'm not sure how you feel about that type of information beign out there, but if I were you, I would be contacting those two sites to see if I can get your information taken down. Potential employers, and the like, may search those sites and misinterpret them. Even if you "win the case", the info on your arrest will stay on those sites. Most employers wont care if you were charged and not convicted, they associate arrest with trouble. They may just throw away your resume after they see you on those sites.
I hope someone is able to help you out here. This is going to be interesting to follow.
