Again, nothing says the drone is armed, only that it's being used in the search. There is wayyyy too much backlash involved in a drone strike on US and this is far too public a case for it.
The precedent for using drones in the US for searches is already set. When and where they're being used isn't shared with the public, and most folks aren't worried. The moment they use a missile from a drone on a US citizen on US soil, that's going to change. There will be far more lawyers contesting the use of drones and the public's apathy will turn to outrage. The feds aren't stupid enough for that.
They've been that stupid in the past.
Just boiling the frog.
