What do you think of the new zapper gun that police are using in Australia?  

Watching Sunrise this morning on television they were discussing the new zapper gun (think it is called Tracker-not too sure) that police were now using. There are many mixed views on this new weapon that police are allowed to use on people. Some people are worried that police might abuse their power and use it all the time on people. However others perceive it as a good thing as many police have been hospitalised or killed by criminals, this new gun will stun the abuser for 5 minutes, therefore enabling police to be safer. What are your views on this new weapon police have?
