She must have a prior conviction on her record. I found it pretty funny that each cartridge carried a separate count.
Oh, possession of ammunition is a federal felony for a person who is a fugitive from justice (maybe the three block run renders her a fugitive); or a person who is a user of illegal drugs (so, if they find pot in the car, and ammo, she's an automatic felon); or is an illegal alien.
I presume this case is NOT a federal case, and speculate that part of Florida law is roughly parallel to the federal law.
The article says bullets, not cartridges.
How are bullets dangerous? She going to throw them at people?
