Reply #17: I have no idea what they publish in their manuals, but the articles says:

[Chemisse]

"It marks the first time that Taser has suggested there is any risk of a cardiac arrest related to the use of its 50,000-volt stun guns, The Arizona Republic reported.

"Taser officials said Tuesday the bulletin does not state that Tasers can cause cardiac arrest. They said the advisory means only that law-enforcement agencies can avoid controversy if their officers aim at areas other than the chest.

"Critics called it a stunning reversal for the company."

Now if you are mincing words: by harmful, I meant can cause cardiac arrest. Perhaps in their manuals they warn of other kinds of harm, like the victims falling and getting hurt. I have no idea. I have never bought a taser.
