Your facebook account could be detrimental to your defense.
As a criminal defense attorney in Houston, I am amazed how much information I can gather on a potential witness via the Internet. Their facebook account reveals a lot about them. They make comments regarding all sorts of subjects. Sometimes they even post stupid comments regarding the case that they are the alleged victim and/or witness. Nevertheless, facebook is a double-edged sword. My clients have been burned with what they have written in their facebook and the pictures that they have posted. That is why I tell all my clients now to "clean up" or delete their facebook accounts before a prosecutor uses it against them at a punishment hearing or at trial. For example, a probation officer may see that you posted that picture of you and your buddies drinking at a party that you tagged and pass it along to the judge. This could be grounds for your probation to be revoked.
