Kind of like Police Quest 1 too. Although it did teach me to type "use handcuffs" fast enough. Also the spelling of "briefcase" and other longer words.
We learned about the Miranda rights, and the PR-24 nightstick. I remember the sobriety test part. We didn't know what a "field sobriety test" was exactly, but we knew it was something to do with drunk drivers. Somehow we managed to finish the game.
I think most people can pick up a lot of clues from context alone.
The things my kids have seen and knew before 6 years old was 1,000 times worse than anything in Leisure Suit Larry. Our daughter was repeating racial and sexual slurs she learned in the cheap "after-school" shes forced to attend.
American parents or society doesn't care about their kids at all in general (did we ever?) and growing up in this broken society is far more mentally damaging for kids than 20-30 years ago.
