CASE 1:

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?
