Question: Were people able to "lock" the Holodeck doors so that others couldn't just walk in on them? I don't recall an episode where the doors were locked that wasn't because of some malfunction. It seems like Lieutenant Barclay, for example, would either lock the doors during his "fantasies" or have some "fail-safe" that shuts the program off when being walked in on. Otherwise, it's just a really dumb thing to do (for him or anyone playing out a fantasy) knowing they could easily be caught.
Question: Kind of a long question but please bear with me. In one episode, Catherine and Vince have to rescue a boy who was being chased by a man who murdered his father. The boy claims to have a letter from his father detailing a crime that occurred and how he was killed for betraying the man. The end of the episode has the boy reading the letter out loud in court. The judge asks to see it and after a quick look over, he gives it to the man who was after the boy. When the man looks at it, there's nothing on the paper but squiggly lines. The judge then has the man arrested for murder. Why would the judge do this? There were no witnesses. All they had was the word of a boy and a piece of paper with nothing but wavy lines on it. No real evidence was presented to the judge at all.
