KNOWING POSSESSING ILLEGAL IMAGES (Footnote)
In closing arguments before a celebrated judge, called out of retirement to hear this case involving a nationally known gay newspaper reporter, I countered the government's "file cabinet" analogy with one of my own: Having these items on the deleted portion of my clients' hard drive where they are retrievable only using a program the government possesses is analogous to a person receiving an unwanted photo in the mail, burning it in his fireplace, and having the government come in the next day, reassemble the carbon atoms using a program unavailable to the general public, recreating the picture, and then claiming that the person still "possessed it."  The judge not only acquitted my client but found him factually innocent as well. This of course resulted in a total destruction of all records; afterwards my client was able to truthfully say that he had never been arrested for that offense.

UNDER 18 (Footnote)
Absolutely do not attempt to "mentor" a teen under 14. If that is your desire go through an organization like Big Brothers where you will meet the youth's parent first. Be aware that penalties for sexual activity with a person under the age of 14 increase exponentially. The cops know this, and frequently will pose as a 15 or 16 year old and then, at the last minute (after you have agreed to meet) change the age of your mythical friend to 13. If this happens--if your "friend" suddenly confides in you that he is only 13-- you must know that he doesn't exist and his persona is being created by law enforcement.
