Sonic Blaster Causes "Involuntary Urination"... hmm.

From Business Day Online:

Polish anti-hooligan squads are ready for the European championships in Poland and Ukraine.

The football fiesta which starts on June 8, have squad members armed an array of weapons ready for potential trouble-makers, from testicle-biting police dogs to sonic cannons capable of inducing involuntary urination.

The English-language Krakow Post newspaper asserted in an editorial that local law enforcement agencies were more than ready to tackle any hooligan threat at England's southern Poland base camp.

English fans who are known for hooliganism are not expected to arrive in Krakow in significant numbers, with England's Group D games all taking place in Ukraine.

You can also read it in the UK Sun. 

Or read the original article in the Krakow Post. 

Want to read more about these cannons that make people urinate involuntarily? Click it. Apparently you can purchase these, although the link from this article isn't working. If I find it I'll post it. Everyone out there talking about wanting to become incontinent... I got you covered. ;)
