Look, morally I couldn't care less.
In terms of risk assessment, however, my genuine opinion is this: Most of those subhumans who've been making our countries unsafe probably didn't even know Al Baghdadi. Under different circumstances, I reckon, they would've had done what Al Quaeda did in the wake of Bin Ladin's death: Pretend they didn't need to care about it, pretend his death didn't matter.
But now they've been given plenty of reason to care. Now it matters.
