Scaremongering, pals. All forensics is mostly bullshit to begin with, and even if this works as stated it takes 30 seconds on a stationary target so uhhhhh yeah. Dont feed the paranoia machine.
The more likely use of this is as “evidence” for framing folks the state decided was already guilty, not actually catching anyone.
