When an intelligence or law enforcement organization describes something as a "tool in our toolbox," run for the hills. That's the shit that has brought us blanket police video surveillance, Five Eyes bulk capture of basically every electronic communication on the planet, automated number plate recognition cameras on every cop car (and every third lamp post), indiscriminate use of IMSI catchers, attempting to ban encryption (for all but the elites, of course) over "going dark" on terrorists, military weapons and tactics for "local" police, etc.
It's a euphemism for turning democracies into police states, full stop.
