I'm not saying goals were achieved.
Achieved or attempted, makes no difference. If you hypothesize a deliberate act, it must have had a goal.
A public fear factor is increased.
Where's your evidence that any such thing occurred? The guy next to me in the locker room at my gym runs the Boston Marathon ever year, and has for decades. He's 80 years old and still running. That year he was about 15 minutes behind the bomb. The following year he couldn't wait to go back and run it.
And as has been said, the
attempt to create fear is a credible goal, and was the primary stated goal of the people accused of perpetrating it. You haven't shown that your hypothetical Powers That Be need to have that as their goal, nor why they would stoop to such a comically ineffective and elaborate method of attempting it.
Especially where media spin factors in.
Whereas
conspiracy spin factors don't seem to bother you. Again you're still stuck in the mindset that anything that isn't aligned with the majority belief must necessarily be reliable.
Fear can be used to control behavior, votes, lynch mobs, armies, etc.
Indeed, irrational fear of some supposed Powers That Be can even be used to persuade someone to adopt unsupported and irrationally alarmist beliefs and give attention to people whose only stock-in-trade is that they aren't the majority, and who otherwise would receive practically no attention. Given how easily such fear can be created and maintained by conspiracy theories aimed at gullible people, what have you done to ensure you yourself aren't being controlled in such a way?
Conditioning populace to martial law style operations in their homes and neighborhoods also comes to mind.
So we're just going to ignore the huge public backlash against military tactics and weapons finding their way into law enforcement? That's pretty strong evidence that you don't just "condition" people that way.
Can these be applied to a hypothetical profiling...
Geez, how much longer are you going to avoid giving a straight answer? At this point the answer is pretty obviously going to be that you haven't thought out your claims well enough to give a real answer, but it would be nice if you admitted as much now instead of dragging out the discussion for another five pages with some pretty obvious ham-fisted attempts at evasion.
