Why this stamp.

• “British police arrested five men near a US air base on suspicion of explosive and terrorism offences on ​Sunday after a tip-off that three vans had been heading to the military airfield which has been used to strike Iran...” names a checkable occurrence — actor and action that can be verified on the record. The desk is grading that documented event, not every surrounding take.
• LinkedIn is reporting something that already happened, not a tip sheet or preview. A dated action, filing, score, or official step is on the page.
• The desk stamp Real is on the documented event — not a blessing of the surrounding spin. Spin can be wrong; the occurrence still has to clear the Real bar on its own.
