Amanda Bynes is not psychiatrically unsound enough to be committed
Though Bynes was taken to the hospital following her arrest for throwing a bong out her window when a police officer came to her apartment in NYC, she was quickly released from the hospital and sent to the booking station instead. The doctors didn't feel a hold was necessary.
According to TMZ, Bynes has not been diagnosed with any mental illness, and was very lucid in court. She understood what was going on and spoke clearly when answering the judge's questions.
However, Bynes' parents believe she may be bipolar or schizophrenic, and they're said to be looking into a conservatorship, like Britney Spears has.
