Facebook Group Creator detained by Croatian Police

Recently, A man who launched a Facebook group critical of Prime Minister Ivo Sanader was detained and questioned by police. This event brings up some interesting points regarding the interaction between the law and the worldwide web. First of all, it calls attention to the ever growing power of social outlets such as Facebook, Myspace, etc. The fact that a Facebook group was considered a threat to the prestige of the Croatian government shows this growing power. This power can be attributed to the amount of people that one is able to reach just through creating a Facebook group and the amount of people that utilize Facebook in general. This very fact calls into question whether or not the Croatian government may have overstepped it's boundaries by trying to regulate sites such as Facebook. Is this not a violation of free speech? Do people not have the right to express their opinions? What is particularly interesting is the contradiction between this act and what is stated in the Croatian constitution.
Article 3 [State Values] states:
Freedom, equal rights, national equality and equality of genders, love of peace, social justice, respect for human rights, inviolability of ownership, conservation of nature and the environment, the rule of law, and a democratic multiparty system are the highest values of the constitutional order of the Republic of Croatia and the ground for interpretation of the Constitution.

Does the stripping away of ones ability to express themselves not contradict the ideals of a democratic society? It almost seems hypocritical for the Croatian government to lay out these principles in their constitution and then regulate free speech as they have.

Rather than actually detaining an individual, the Croatian government may come up with other deterrents to stop people from using the internet to bash their government. For example, a disclaimer could possibly put out that these groups will be removed immediately from facebook as soon as they were posted. This could potentially stop people from posting them in the first place.

Overall, this event can possibly serve as evidence of increased internet regulation. This increased interenet regulation may be eventually correlated to the loss of "inalienable" rights.
