Twitter To Appeal Turning Over Protester's Messages

Posted by samzenpus on Thursday July 19, 2012 @07:08PM from the keep-your-hands-off-my-tweets dept.

angry tapir writes "Twitter plans to appeal a ruling to turn over the once-public tweets of an Occupy Wall Street protester charged with disorderly conduct, a case the company says threatens the First Amendment rights of its users. A New York Criminal Court judge ruled last month that Twitter should turn over the tweets of Malcolm Harris, since his messages were public and are not the same as an email or a private chat, which would require a search warrant."

Can the Public Become Private? by ohnocitizen · 2012-07-19 19:13 · Score: 5, Interesting

Imagine putting a sign on your front lawn. A month later you bring it inside your house. Since the sign was public, does that mean the police no longer need a warrant? If twitter loses this appeal, the answer to that question will be no. It is essentially saying anything made public can never be made private. Now, if someone took pictures of that sign on your lawn, that's another matter. So a snapshot of a public site would be fair game. So much so, I wonder if the police monitor tweets and store potentially interesting ones?

  This is disorderly conduct. It is several orders of magnitude less than threatening to kill someone. Flipping off a cop, pissing in the street, having a temper tantrum, or being drunk in public are items that would normally be grouped under this crime. In the court that I used to work at the penalty was typically a $100 fine and 1 day in jail (which was credited even if you bailed out immediately). It is basically the judicial system's version of a time-out. With a lawyer, it would almost always result in a deferred sentence (no criminal record).
  There is no value to the state in searching for evidence to this crime. If the state needs anything more than the statements of witnesses, the statements of the cops, or voluntarily turned over camera footage, then the prosecutor is wasting his or her time and scarce resources.

  My take on it, which I may revise upon further consideration... To view the sign itself requires a warrant-- however, all previously recorded imagings of the sign are fair game. This is under the assumption that it was originally intended to be public, and not, say, simply in transit or the like.
  In the context of Twitter... I suppose this would mean I have no objection, though the inability to remove something from the public sphere is a concerning thought.

  It is doubtful that that phrase, without context, will be used against you. Words on their own have no standing without context. Now, if you pull a knife, wave it menacingly at an individual and scream "I'm going to kill you!", now you are talking about something that will get you in trouble. People scream, whisper, shout, say and text 'I'm going to kill you' all day every day with no repercussion and there shouldn't be any repercussion, because that phrase is a well known idiom.
  While it is true that you can't pull words back from the past, you can, figuratively, unsay most comments. How successful the unsaying is debatable and dependent upon the comment, to whom it was said and in what context you made the comment you wish to retract.

Duh-Have the lawyer download the "public comments" by Anonymous Coward · 2012-07-20 02:23 · Score: 0

If it really is public, why doesn't the lawyer download these messages himself? Duh. If they want an "expert" to do it, I'm available for US$2000/hr.
Seems that "public info" should mean "get it yourself" OR twitter can charge whatever fees they like to provide it - outragous fees would be a good idea.
If the data isn't available anymore, than it isn't "public" is it?
Compelled to Research? by Anonymous Coward · 2012-07-20 05:30 · Score: 0

Usually there is some protection from being required to do research to provide information to a court. Having an item at hand and knowing that you have it at hand is one thing. Requiring a party to dig into databases and search for older messages costs money and may not be within the power of the courts without providing compensation for the work done. When any officer is under oath for such a petty communication it would be true normally to reply that he does not know if the material exists. Imagine ordering someone to go through all communications on Twitter and determine if a certain individual sent a message. One never knows how many identities one might use on that kind of social site and many people use net cafes or libraries or their friends computers. To testify that one has diligently researched for messages is a bit absurd in a way as it simply really can not be properly done.
