Pretty casual about committing federal crimes.

Argumentum ad legem.

Was slavery moral because slavery was legal?

Apart from that,the device's raison d’etre is committing federal crimes, namely violating the 4th amendment rights of private citizens. Previous case law has found mining historical cell phone location data to be a 4A violation requiring a warrant.

Not an american, here in germany you'd barely get a fine if they even bother to prosecute you for using a jammer for a few minutes here and there. But I don't yet have to deal with ai powered surveillance cams by private companies in my city.

Well that is too bad. I am glad it is taken seriously here in the US because wireless jamming is a serious public safety issue.

if the EU maintains it's current trajectory, you'll be dealing with this or a similar problem in the future.
