<human>: *This post is more directed towards any law enforcement redditors.
I found a thumb drive at my college library, so I took it home and looked through it to find a name or any kind of contact information on it. I found a name, face and email, so i contacted the owner. All I said in the email was that I needed to meet with them and they filled in the blank that I found their property. They went of about how that usb had their homework and work stuff. I thought I was doing them a solid by emailing said stuff so they don't get too worried. After that they went off about how there is "sensitive information" on their usb and that they will probably involve the police. I have given the usb to a trusted instructor the owner and I mutually know and I hope that's the end of it. I am now wondering, did i do the right thing or did i dig my own  grave. So far no one has contacted me so maybe nothing will happen. But I am wondering, if any law enforcement does get involved, what would happen?

Give me the gist of the text in a nutshell
<bot>: Found lost usb with apparently important shit and the owner wants to involve police. All i wanted to do and did was return it. What might happen next?
