I have worked in Law Enforcement for 15 Years and have been shot by a taser ONCE! It was for work and was the worst thing I have ever gone through. I felt like crap for a few days after. The police tasers give a person a 5 second ride that feels like a week and a day long. The personal deffense ones give a 30 second ride. Everybody I know that has been hit by a taser can't even think about how bad 30 would be. They are desinged to let a person shoot the taser, drop it and run.
They could be very effective for deffense.
However, there is one thing to think about. In the line of duty, I had to used one once. My partner and I were attacked by a crazy drunk guy (he was actually crazy). Long story short, I shot three sets of probes and only one worked. Clothes got in the way and prevented the taser from working. When it did work it stopped the assault in a hurry but if my life depended on in, I would prefer a gun. JMO
