As communities and government agencies struggle with these new mediums, some choose to criminalize the use of technology to support services for people who are involved in lawful protest, community activism or dissemination of public information.

Many public officials are worried about the growing use of Web 2.0 technologies (like social networking) in constituent/government communications. Tweet3po is dedicated to the dissemination of hyper-local, relevant, actionable information to everyday citizens. We do not advocate using these technologies as an alternate way of reporting or responding directly to emergencies. As always, please contact your local law enforcement agency directly by dialing 9-1-1.
