"When a politician claims for example that 'crime is down' since he implemented a certain policy, it is the professional investigative journalist who knows the raw data on which this statement is based (criminal incident reports) and who asks for verification. He or she can then go to other sources to question the veracity of the data. The reason I specialise in the intricate details of bureaucracy isn't because I have a passion for paper-pushers, but rather because I need to know all the types of information collected, by whom and where they are stored so I can get my hands on them. A statement isn't a fact. Even when the person making the statement is an authority he or she still needs to provide evidence or proof that what they say is the truth and a professional journalist should be asking for this proof and supplying it for public scrutiny. All this accumulating of statements, data and information which then has to be verified takes time. But this is the only thing a journalist does that marks him out as a professional. It's the only reason anyone would choose a well-known newspaper's website over an unknown blog. The newspaper as a brand has built up, over time, a reputation for challenging the powerful and giving people meaningful, true information. The press is not like any other business and what it sells shouldn't just be rehashed press releases or celebrity gossip, but the civic information necessary for people to understand their society and participate in it. It is a check on political and financial power, or at least it should be."
