wasn't Shawn 18 when he was arrested ?
"The Ghost in You"
1995
the opening sequence is him getting arrested and Henry saying
"This officially ends your chance at being a cop"
and Shawn responding
"Let's be honest, I gave up wanting to be like you a long time ago"
and i'm saying this like i have all the episodes committed to memory but the truth is i just looked it up and watched it online to confirm

Yep! After the statement of what Shawn's mother is going to think, Shawn said, "I don't know. Do you have her new phone number?"
Henry lost it and said, "That's it. Will someone please book him?" And it was almost Lassiter who booked Shawn, but it was Henry who arrested him. It was later in pilot where Lassiter questions Shawn about the arrest.
"I was eighteen."
"Oh, I guess we can erase it out." This means that it is in Shawn's personal record, so employers know that Shawn got arrested! Employers don't like hiring people with a criminial record, especially in law enforcement.
