Lethal Tasers and Bad Logic

Heard this on NPR this morning:

[The Taser] is not a lethal weapon. Nobody has ever proved it has caused a death. - Taser salesperson

Uh, gee, that's not a logical conclusion. You can't assert that something is a fact just because nobody has proved otherwise (...aliens from Alpha Centauri live among us -- nobody has ever proved they don't). At best it would be inconclusive.

But the second statement isn't even true. Google for taser death and here are some of the hits on the first page:

Apparently, hundreds of people have died from this "non-lethal" weapon. Is it safer for the person it's used on than a gun? Sure, but that's no consolation for those who have died.
