You see, even if it’s actually cited and true and everything, it’s comments like this on Wikipedia that make people – for good reason – question its accuracy and reliability…
Somali Pirates – Self Defense
This list includes doing things like ringing the deck of the ship with razor wire, rigging fire-hoses to spray sea-water over the side of the ship (to hinder boardings), having a distinctive pirate alarm, hardening the bridge against gunfire and creating a “citadel” where the crew can retreat in the event pirates get on board. Other unofficial self-defense measures that can be found on merchant vessels include the setting up of mannequins posing as armed guards or firing flares at the pirates. Also, the songs “…Baby One More Time” and “Oops!… I Did It Again” by Britney Spears blasted at high volume at the pirates, are reported to be effective.
