So why are these shield laws important, and why should journalists be afforded this protection in the first place?
One of the basic defining principles of a democracy is a free press. If information is being stymied by the government, or the political conditions make it impossible for people to engage with the press then the public is robbed of all the facts they need to make an informed decision. Much of the work that journalists due relies on a trust relationship between their contacts, and the material uncovered through the investigative process is not dissimilar from that of detectives. Unless there are protections established than journalists can easily be subpoenaed and forced to do the work of law enforcement thus muddying their position as the Fourth Estate and the trust they have worked so hard to establish.
