Taser International is involved in a lawsuit regarding naked short selling:

"According to the seventy-page Complaint, the defendants' illegal naked short selling of TASER stock flooded the market with counterfeit TASER shares. For example, although in 2005 TASER had authorized and issued only approximately 60 million shares of common stock, more than 80 million votes were cast at the company's annual meeting."

20 million shares sold via naked short selling!
