19 April 2017 – The Metropolitan Police appears to have handed the full names and home addresses of every FAC and SGC holder to a marketing agency promoting the commercial Smartwater property marking and tracing product.
I am investigating this with my day job hat on. If you have received one of these leaflets and are concerned about the implications of your details having been sold on to a commercial third party by police – contrary to what Firearms Form 201 says, on page 7, in the data protection statement – please contact me at work: email@example.com
Smartwater is basically invisible ink. You mark your property with it and if it is stolen, and later recovered, police can read off who owns it using UV light.
