we have them here too and they've also killed and sometimes theyre not even effective for the purpose as this news article shows. a suspected car thief brandishing a knife so they say, took 4 tasers and 3 marksmen firing 9mm hollow point ammunition. news report. http://www.dailymail.co.uk/news/art...id-fail-halt-knifeman-taken-hail-bullets.html
For the most part they are pretty safe , more effective than pepper spray and much less effective than a 40 cal. bullet ,thank God . The problem is there being over used as quick go to in unnecessary situations . There being overly used . And with people with an underlying heart problem , they can be fatal . People think voltage kills , and that something with 100,000 volts sounds deadly . The truth however is it's current that kills people by electrocution . These devices carry very little lethal current . And have become seen as so safe and reliable that the mentality is taze first and ask questions later.
