The officer arrested Packingham, as a 2008 state law bans sex offenders from using "commercial social networking Web site [s]" if they "know" that minors can access it.
The case, which the court will resolve by June, is Packingham v.
The Supreme Court on Monday appeared likely to strike down a North Carolina criminal law that bars people on the state's sex offender registry list from "accessing" social networking websites.
"The law does not operate in some sleepy First Amendment quarter", Goldberg said.
North Carolina received friend-of-the-court briefs in support from 13 other states as well as state and municipal government associations and groups whose mission is to stop child predators.
Florida's law is a little different from North Carolina's.
More than 3500 attacks on refugees in Germany in 2016
More than a million people were admitted into Germany as part of an influx of refugees that began to hit Europe in early 2015. As the BBC points out , 280,000 asylum seekers arrived in Germany in 2016, down from more than 600,000 in 2015.
Furthermore, says Stanford law professor David Goldberg, who's representing Packingham at the Supreme Court, "Everyday Americans understand that social media - which includes Twitter, Facebook, Instagram - are absolutely central to their daily life and how the First Amendment is exercised in America today".
The four liberal justices seemed concerned about how broad the North Carolina law is, one saying it "dramatically" limits free speech. He plead guilty to charges of taking indecent liberties with a child, was given two years' probation and put on the sex offender registry.
Supporters of such laws say they aren't violating sex offenders' free speech, merely the place and manner of their speech, but the trouble arises in laws that are written so broadly as to encompass the entire internet - and perhaps in 2008 it was not clear that virtually every website was going to have a social media component within a few years.
Packingham landed in hot water with state authorities again after he took to Facebook to celebrate the dismissal of a traffic ticket.
An intermediate state appellate court overturned his conviction, but the state supreme court reversed that ruling and reinstated his conviction.
"The practical effect [of North Carolina's law] is to bar registered sex offenders not merely from the school, the playground, and even the town square, but from entire regions of the country where their fellow citizens are gathered for the objective of information exchange about any and all subjects of human inquiry", says a friend-of-the-court brief filed on Packingham's side by the Electronic Frontier Foundation.
Philippine court orders arrest of president's leading critic
She did, however, say that she wanted to go home first to say goodbye to her family and prepare her things for detention. She also acknowledged her supporters and alluded to recent events wherein detainees had been killed while behind bars.
As the youngest member of the court and one who spent time as dean of Harvard Law School, Kagan demonstrated the most intimate knowledge of social media - at one point noting that the law's exceptions for chat rooms and photo-sharing sites created "a constitutional right to use Snapchat but not to use Twitter".
A police officer in Durham, North Carolina who was working to hunt down sex offenders online read the post.
It's amusing because if God cares about traffic tickets but not "indecent liberties with minors" (which is what Packingham pleaded guilty to), then we all live in hell.
Other justices, however, were more skeptical about the state's arguments. "This has become a crucially important channel of political communication". Justice Sonia Sotomayor questioned the premise that the law is necessary to prevent sexual abuse of minors. She suggested the measure might bar people from reading President Donald Trump's Twitter messages. Kagan said. "Because if I would have said, like, where the most risky activity takes place, it's in chat rooms and via photo sharing".
The case deals with the unique situations of sex offenders.
I don't think we want to live in a world where committing crimes gets you banned by the state from social media.
Xenophobic Violence Erupts in South Africa
The Majority Leader said he did not understand why Ghanaians were being accused of taking over South African jobs. Former Minister of Aviation, Femi Fani-Kayode has warned South Africans against further attacks on Nigerians.
Justice Anthony Kennedy said the discussions on social media are "greater than any communication you could have had even in the paradigmatic public square".
