Everybody has read the What topics can I ask about here? page as we all need clarity on whether a question will be welcome before developing it. The rules forbid questions about "the future", they invite questions on "historical events", and explicitly allow "current political history".
Some questions about recent events have been accused of violating an unwritten ban on "current events". This inspecific label applies to recent history, the present, and the near future, which must be treated differently. Questions on the future are off limits, and those on the present moment are allowed at least on political topics. Past events are of course the main attraction on this site.
There is no delay after an event before records are manifest. Information like chronologies and measurements are in the historical record immediately. Historians are forever appearing on talk shows to remark on current events. There is a substantial academic subfield called contemporary history, which was also practiced by the ancient Greeks. Nonetheless, there are doubters (How long before an event gets into history?, How old does an event have to be to be considered 'History'?).
We have no rule about recent history and the lack of clarity is a problem. If you intend to downvote or complain about questions on recent events, please answer with the rule you would like to see adopted. I will add an answer for "recent history is on topic".
