Canadian Police Use Cell Tower Dumps To Text 7,500 Possible Murder Witnesses

from the new-phone-who-dis dept

Every so often, government entities are efficient despite themselves.

In a move they're describing as "extraordinary" and "unprecedented," Ontario Provincial Police will send text messages to about 7,500 people on Thursday to ask for information about an unsolved homicide.

Investigators are calling it a "digital canvass" — the high-tech equivalent of knocking on thousands of doors for information.

The police are utilizing "dumps" from cell towers in the area to obtain these phone numbers. And that's all they've obtained, apparently. Using the list of connected phones in the area at the time of the murder, the police are sending text messages asking recipients to fill out a website questionnaire to help police find the killer.

As much as this might seem like an intrusion, it's probably preferable to the alternative: sending out dozens of officers to question potentially thousands of witnesses. Obviously, it works out well for the police. But it also works out for citizens. Nothing obliges anyone to respond to the unsolicited texts and answering a few questions on a website is far less annoying than being questioned at home by officers peeking through open doors to see if they can spot anything resembling indicia of criminal activity. Why make the entire day a waste? Why not make a few ancillary arrests while investigating an unrelated crime?

Unfortunately, it appears ignoring the message (or sending back "UNSUBSCRIBE") isn't going to keep the cops from using your phone for their communications.

Investigators will also consider calling the numbers of people who don't respond voluntarily, but they would be required to obtain another court order to do so.

The other troubling aspect is that the police obviously have no interest in destroying the phone data they've collected. It appears this will be held onto until the investigation is closed, even though the majority of the harvested numbers -- if not all of them -- will have zero relevance to the investigation other than their proximity to the crime scene.

The police have stressed that responses are completely voluntary, but the plans for follow-up calls suggest the opposite. On the plus side, if someone doesn't want to speak to a cop, getting removed from the list is as simple as filling out a few questions on a website. No details were provided as to how much personal information respondents will have to turn over, though, so this exercise in government efficiency could become just another data-harvesting method. If not subjected to strict controls, any names collected could be run through criminal record databases in hopes of finding active warrants or unpaid fines. If so, it will be tempting to handle more investigations through tower dumps, text messages, and website questionnaires -- what with all the extra arrests and revenue generation that may result from bulk texting.

    This is REALLY lazy, and it endangers people

    There used to be a time when police agencies employed detectives, who would, y'know, go out and detect. They'd use intelligence, persistence, experience, instinct, and reason to figure out crimes and identify suspects. These clowns -- these incompetent, LAZY, clowns -- are using spam. Whoever is responsible for this should be immediately fired and blacklisted from public service for life.

    Second, by compiling this list, they've also compiled a list of people that's also highly useful to the murderer(s). Granted, it's a big list, and it seems unlikely that the murderer(s) will try to kill 7,500 people in an attempt to silence any witnesses...but they don't have to.

    Oh, and third: one or more of those phone numbers might belong to the murderer...who might choose to respond with "helpful" eyewitness testimony that is of course completely fabricated.
