Can you get someone in trouble with the law for these two things?

Ok, so these 2 situations really happened and a friend doesn't believe which one if any of them, you can get in trouble for. Plus I have to do these situations and a few more for a CJ/Law class final! Please help me out! Thanks!

Situation 1: A friend hacks into another friends twitter. The friend's twitter than was hacked into doesn't keep her password private. She also writes about all her other friends on this twitter.
Now the friend who hacked into the twitter does NOT write anything or do anything at all to the twitter. The ONLY thing she does is read the tweets written by the other friend.

Situation 2: 2 friends buy concert tickets. 1 friend keeps them at her house for safe keeping. Friend #1 decides she doesn't want to go anymore due to money issues and wants to sell her ticket that she has paid for. So friend #1 is selling her ticket. Friend #2 takes it upon herself WITHOUT asking friend #1 and tries to sell friend #1's ticket for her. Friend #1 is upset by this and Friend #2 doesn't think she did anything wrong. Legally, the ticket is NOT Friend #2's. So can she sell the ticket that she did NOT pay for and its NOT hers?

Can any of these friends get the other in trouble with the law or sue each other?

This is for a CJ/law class! I have to research these plus many more for a final!
