I a in south carolina, greenville county.I was arrested for discharging a firearm within city limits. Someone left their gun in a restroom at a bar/restaurant. I actually thought the gun was a toy. The woman before me in the restroom said jokingly someone left their toy gun. I went into the rest room and stupidly picked it up and it fired into the floor. I told all this the the officers. The woman also told the officers she believed it was a toy also. I also told the judge the same thing apon release. I am an adult woman with no prior criminal record, even traffic violations. What can expect? Any advice would be appreciated. Should I retain a lawyer? Thank you for the advice.
