I'm going to look up my friend in a database to find out if he is a real person and if he has a record
Why do you want to know if he has a record?
I'm curious and I want to hold my friends accountable
It is okay to be curious about your friends but you should be careful about doing to much too find out about them. It would feel like you are violating him to go so far as to look at a database.
Yeah but I know what I'm doing
Are you sure?  It seems like you're needlessly suspicious of this person.  If you trusted them enough to be friends in the first place, why are you acting like this now?
