Are police officers aware of the potential lethal damage teasers can do?

First off idiot it's called a taser not a teaser use the spell check. Like everything else the media takes a story and blows it out of proportion. Hundreds of people are tased by police everyday in this country with no ill side effects. With out the taser alot more people would be getting extra breathing holes to their cranial cavity courtesy of MR. Glock.
