Is AUTHOR wrong in the post ? POST : 
I let this guy live with me free and he took my car without asking and I found him took it back.  He left his bags inside and when I got back I decided to look through it because after taking my car why would they be steal too. Sure enough I found my snap on tools inside. 

He has more bags at my house and I couldn't help it I went through another one and again more of my tools. So now I'm wanting to literally go through all of his bags but morally should I tell him an then do it or do it then tell him? I know what the laws are but just from a moral perspective
