Can social media or internet information be used to prove a case against me in court?

Transcript:

Absolutely. I tell all my clients when they ask me, should I talk to law enforcement? I tell them many a person has talked their way into the penitentiary. No, you should not talk. In the same way you should not email. You should not be on social media if you’re looking at federal charges because any of those things can be used against you in a court of law.
