You're right about FCC laws, but there are non-FCC laws, too, such as penalties for willful interference with federal/state emergency communications.

I'm wondering if this device would cause issues for a nearby person's emergency communications. Seems potentially really bad.

You seem to be pearl clutching a bit too hard. I am positive there are no legal issues.

[caminante]

It's not "pearl clutching" when there are enforceable laws like 18 U.S.C. § 1362.[0]

Were you even aware of this?

Can you actually cite a legal opinion about the device or similar applications? Otherwise, I'm assuming you are speculating, too.
