Right there's another gotcha with the data. They gave 15-60mph data in :30 minute increments.

"This would still identify officers blocks or get within a couple blocks of their home for those with take home cars. Would speeds of 15 miles per hour or more but only pings on the :30 minute mark, so one ping per hour from 2019 until the end of April work for you?"

Even gave them this SQL to run to get around that problem but they never got back to me, heh:

  WITH immobile_pings as (
  select count(*), vehicleid, round(xcoord::numeric, 3) as xcoord_rounded,
    round(ycoord::numeric,3) as ycoord_rounded,date_trunc('day', datetime) as day
  FROM gps_table
  WHERE speed = 0
  GROUP BY
    vehicleid,
    xcoord_rounded,
    ycoord_rounded,
    day
    having count(*) > 1440), --4 hours
  day_counts as (
    select count(*), vehicleid, xcoord_rounded, ycoord_rounded
    from immobile_pings
    group by vehicleid, xcoord_rounded, ycoord_rounded having count(*) > 15 -- 15 days
  )

>other purposes.

Just say "Stalking their ex partners" its fine we all know about it in 2026.
