Any criminal accusation involving sex is a very serious one. Prison time and heavy fines are enough to worry about for any criminal charge. For sex offenses, however, the punishments seek to shame you and hinder you long after you complete your sentence — sometimes for the rest of your life. You are required to register in a public database, where anyone with internet access can see the details of your crime.
Sex crimes also carry a very negative stigma, and jurors may walk in with certain prejudices. However, sex offenses can often be based on false or exaggerated claims. A skilled attorney can overcome the prejudices of the jury and point out the weaknesses in the case.
