Prep, UK

Well, Bristol England, it is good you are prepping for the Zombacalypse, but your country is going to have have some major rights reforms on individual self-defense if you want any chance of a good result.

But they have codewords for radio and TV broadcast to disseminate info to authorities without causing a panic.  Like we used "Doctor Redbird" at the hospital to alert staff to a fire.  If you ever heard a PA system at the hospital ask for Doctor Redbird and then a buncha janitors ran past with fire extinguishers, that is why.  Or "Hey Rube" as the call of Carneys to indicate there is trouble at the county fair.
