Setting fires in an old lady's drive way is not a great idea. The police are holding Amanda Bynes in a hosptial for what is called "5150" which means being involuntarily hospitalized for psychiatric reasons. The police asked her numerous question and due to her whacky responses they deemed it only right to have her hospitalized. She can legally be held for 72 hours.
The elderly woman described Amanda setting a small fire in her drive way and carrying around a "small red gas tank" The police also reported that Amanda's clothes were bruned.
If this isn't Rock Bottom I don't know what is.
