I believe in Florida defendants are found incompetent to proceed if they do not:

1. Understand the charges/allegations against them.
2. Comprehend the possible penalties.
3. Understand the adversarial nature of the legal process.
4. Have the ability to disclose to an attorney pertinent facts that would aid in their defense.
5. Exhibit appropriate courtroom behavior.
6. Have the ability to testify relevantly.

I would imagine Doony failed 4 and 6, and was borderline in 3 and 5. In his damaged brain he believes the charges are 100% false, he is pro se because lawyers do not listen, and his defense strategy has been to have each judge removed.
