Legal Answers
4 Questions Answered

Q. How do you get a record of “no record” from an arrest that was dismissed? In New York City specifically.
A: Go to the criminal clerk in the courthouse where the case was located. Request a Certificate of Disposition. They should be able to find it with your name and date of birth; and, if not, they'll give you a "no records" certificate. Should cost you between $5 - $15.
Q. I like to know what do this mean. OFFICE MISCELLANEOUS No Type Test, People Cert Comp Filed/ready Bail cont
A: It means the people provided their certificate of compliance under the new discovery laws and are ready for trial. Your bail was continued from the prior date (remains the same).
Q. Is it illegal to carry a bb pistol around on your person in upstate New York?
A: Typically no. But if you use it to harm or threaten someone it can be unlawful possession as an "imitation pistol" (in addition to charges related to the threat/harm). You also can't have it on school grounds or certain other properties. If you're carrying it openly and causing a scene you can get a disorderly conduct, among other charges. Basically just use your head, keep it in a backpack or bag, and you'll be fine.
