With what happened last June, very commented in the media, as we discussed last month (), a Hamburg teenager summoned his birthday party by the social network of Facebook and was attended by 1,600 people, pretty much, therefore, today certain forward-looking steps have been taken. The Minister of Interior of the State of Lower Saxony, has said that when security and public order are threatened festivals through Facebook requests shall be prohibited in advance, says that adolescents do not know on many occasions that may assemble and why it has demanded that schools that guide them in these topicsespecially of the dangers which may arise. On the other hand he has raised that councils take responsible for consequential damages and costs of these parties and meetups, parents and representatives of the convener, perhaps get to pay a huge amount of euros can cause consciousness in the use of social networks and we could start either unfounded education from the core of households. To conclude, we acotamos another event that happened during the weekend of Easter in Pentecost, where police had to dissolve various festivals which was attended by approximately 800 people, there were 41 youths arrested and registered 16 wounded with distinction, all for a call from Facebook. What nobody knows, is if the unknown guest who confirms and attends the appointment by an invitation to your social network, may have some pathological or mental imbalance that causes the party to end in disgrace or, simply, goes with the intention of causing unrest.
