Detect Authority and Shatter the Gate

Can Detect Authority at [ani] be used to protect Shatter the Gate? Shatter the Gate is "on" the Baali, but I'm not sure if Detect Authority works for cards on a minion.

Detect Authority [TR:C]
Cardtype: Reaction
Discipline: Animalism/Serpentis/Thaumaturgy
Requires an anarch.
[ani] Only usable during a action directed at a minion or location you control. The action ends (no cost is paid), unless the acting minion burns 2 blood immediately.
[ser] +1 intercept.
[tha] Reduce a bleed against you by 2.

Shatter the Gate [HttB:C]
Cardtype: Action
Clan: Baali
Burn Option
+1 stealth action. Requires an infernal Baali with capacity 9 or more.
Put this card on this Baali. A vampire with capacity 6 or more may burn the Edge to burn this card as a action. If this Baali has three Shatter the Gates, burn them all to give each other Methuselah a shattered counter. A Methuselah with any shattered counters burns 3 pool during his or her untap phase.

No.
Secure Haven won't protect the Shatter the Gate cards either.

Correct. [LSJ 20080602]

That's unclear Detect Authority can be used during an action targetting Secure Haven, but a minion with a Shatter the Gate and a Secure Haven can have its Shatter the Gate burned, despite the Secure Haven. [LSJ 20020502]
