the reg reports in a scottish prison, prisoners are blocking IMSI catchers
with aluminum foil because the IMSI catchers were in plain view. Using the
foil, they blocked the IMSI catchers line of sight.
Prisoners can be so innovative!

interesting tho, that it is just being reported now, but the source was a
report from 2014
