Take one Polish traveller, without sleep for more than 24 hours, lost in a supposedly secure area of an airport for more than 10 hours, confronted by 3 police officers who cannot communicate with him and you have a recipe for disaster. Tasered 5 times for a total of over 2 minutes; is it a surprise he died? The cops big fault? Getting caught on video for the world to see.
Suggested test method for Taser testing:
Take one very senior police officer, face down on concrete
Stand one sumo wrestler on officers back
Taser officer for two minutes, wait five minutes and repeat two more times
This test should also be applied to the manufacturers CEO, and to any politician voting in favour of the device. It is perfectly safe after all, the manufacturer guarantees it.
