A court trick

This time you are one of the inhabitants of the island. There was crime committed and people think you did it. At the court you can say only one sentence to save your life. So what do you say?

• If you were a lier (the court does not know that) and you were innocent. It is known that a swindlecant did it.
• The same situation but you are guilty.
• If you were an honester (the court does not know that) and you were innocent. It is known that an honestant did it.
• If you were innocent and everybody knows that the one who did it is not normal. Normal people sometimes lie and sometimes speak the truth. What sentence, no matter if you were an honestant, a swindlecant or normal can prove your innocence?
