Correct. Wikipedia editors are not journalists and have no access to the kind of fact-checking process that reporters have. This is why we publish only what reliable sources have already published.

My interest here is rather in people's behaviour. The user who cut the information has, in my view, made numerous mistakes. Since the Verifiability policy will not in any case prevent the making of mistakes, here's the question to the class.
User:81.157.14.152 didn't follow best practice here. Enumerate the ways in which best practice was not followed.
