Public transit lines in the United States have been bugged to capture audio. Legislative action is occurring in many jurisdictions which would allow various criminal gangs masquerading as "law enforcement" agencies to admit they use these systems. Sorry for your laws.
Linked piece is classic disinfo: any vehicle – bus, plane, train, barrel falling down a waterfall – with a SmartPNohe on board – is 'wired for sound.'
Sure, but the lulz is in the temptation to abUSE it has become so great that now they gotta ask permission to admit they use it to actually use it in the way they want to.
