Police officers often take a lot of flak for their actions after being thrust into volatile situations.
Department policy often outlines when use of force -- from a gun to a baton -- is warranted, but the increased use of Tasers has created a grey area where internal investigators often struggle to balance an officer's right to protect himself and others with the use of high-voltage electricity shot into another person's body.
Some of the more high-profile uses of Tasers have turned into punch lines or jokes, like the 2007 "Don't tase me bro!" incident at the University of Florida.
But others, such as this year's death of a mentally ill man in New York City, can have life-changing consequences for the victims and the officers involved.
Here is a list of some of the most memorable Taser incidents:
Two Boise, Idaho, police officers were reprimanded after an investigation concluded excessive force was used on an unidentified man who was shocked in the back and the backside.
But it wasn't the actual shocks that got the officers in trouble. It was their threats to tase the man in the anus and genitals that raised eyebrows. The man, who claimed the officers thrust the Taser into his nether regions, told the Idaho Statesman that he plans to sue.
Police were called to the scene after a neighbor reported a possible domestic violence dispute.
A routine traffic stop got off to a bad start for 72-year-old great-grandmother Kathryn Winkfein.
After being pulled over in Travis County, Texas, in May for driving 60 mph in a 45 mph zone, Winkfein, captured on the officer's dashboard camera, refused to sign her ticket. She then got out of the truck, telling Officer Chris Bieze to "give me the f---ing ticket now."
Bieze can then be seen shoving the woman, something he said was to keep her away from oncoming traffic.
"You're going to shove me? You're going to shove a 72-year-old woman?" Winkfein demanded.
Bieze can be heard on the tape warning the woman about a half dozen times that he would tase her if she didn't stand back, to which she replied, "Go ahead, tase me."
So he did.
Winkfein was charged with resisting arrest and taken to jail. Bieze's boss later told reporters that his officer did everything by the book.
Police in New York City didn't get off so easily last September when a naked man plunged to his death in Brooklyn after being tased.
Inman Morales, 35, died at a hospital after falling 10 stories. Police had been summoned to the building because Morales had threatened suicide.
When they arrived, Morales crawled out a window and onto a ledge, thrusting an 8-foot-long fluorescent light at officers as he went.
A video of the incident shows an officer raising his stun gun at the man who toppled head first off the ledge, prompting gasps and screams from the crowd below.
The officer who fired the electric shock was placed on desk duty while the NYPD investigated and the lieutenant who ordered the use of the stun gun was relieved of his gun and badge.
That lieutenant, Michael Pigott, shot himself in the head a few days later on Oct. 2.
An NYPD official said after Morales' death that department guidelines specifically prohibit the use of Tasers when the suspect is in danger of falling from an elevated surface.
No criminal charges were filed in the case.
