Please help me on how to solve a case

Please explain how the principles of law and dispute resolution can be applied to real-world situations.

CASE 1:

Lance, a hacker, stole 15,000 credit card numbers and sold them on the black market, making millions. Police caught Lance, and two legal actions followed, one civil and one criminal. Who will be responsible for bringing the civil case? What will be the outcome if the jury believes that Lance was responsible fot identity thefts? Who will be responsible for bringing the criminal case? What will be the outcome if the jury believes that Lance stole the numbers?

CASE 2:

Carter was an employee of the Sheriff's office in Hampton, Virginia. When his boss, Sheriff Roberts, was up for reelection against Adams, Carter "liked" the Adams campaign's Facebook page. Upon winning reelection, Sheriff Roberts fired Carter, who then sued on free speech grounds. Is a Facebook "like" protected under the First Amendment?

CASE 3: Annie and Bart are Coworkers. In fact, they share a cubicle wall. Recently, they were involved in a fender-bender in the company parking lot. Each blames the other for the accident, and the two have stopped speaking. Would you advise them to try to settle dispute through arbitration, meditation or with a traditional lawsuit? Why?

CASE 4:
