Just heard on the BBC at 5.40 with their historical updates of the day: Ronald Reagan was shot on this day, followed by an advocate of gun control. This was an editorial choice on the part of the BBC.
If you strike the bias pose, you will state that the BBC has a left-liberal bias and that there is a conscious decision to advance gun-control through this choice of quote. Yet, a number of alternative scenarios are possible. The historical scenario would conclude that the quotation formed part of the original news report, and that this is repeated now. There could have been a selective bias at the time, which is now reinforced, but we cannot be sure that is the case. Alternatively, the quote was chosen by chance as padding, as the editor was pressed for time or because it was a complete sentence or nder a number of technical criteria.
BBC bias is possible, but not proven in particulars, but clear in the aggregate.
