airports, the most surveilled places in an already hypersurveilled world... thus the only people who can tinker with the outlets are the airport... and the FBI/CIA/etc.
And as a targeted attempt to break into a phone, it's useless, as you can't predict who will charge their phones at the airport outlets.
As a delivery mechanism to surveil all the phones, it's conversely too small a group - and also useless, as the phones are hypersurveilled anyway.
So what's with the fearmongering? Why? Just to feed the clicks at exploitation media, inc.?
