Giving LEOs tasers without them having a through and intimate knowledge of the science, understanding of conditions and situations that can make the technology more lethal, and providing for consequences when the item is misused should cause the general public great concern.
There are many, many instances where technology has been implemented and used by law enforcement that are essentially a fraud on the general public. For example, while the science is correct and indisputable, the misuse, lack of understanding of conditions and situations, lack of concern over calibration and accuracy by most LEOs, and lack of consequences based on misuse to convict innocent civilians, the use of "traffic radar" is one of the biggest scams pulled on the travelling public by overzealous law enforcement. When properly used, the results are indisputable and the manufacturers of these devices refuse to admit their fallacies. Unfortunately, most officers have not been trained in the proper use of the devices or of conditions that they should avoid in order to prevent erroneous readings. Additionally, as the devices (especially handheld) are bumped, banged around, jarred and otherwise abused in everyday usage, the calibration is quickly and easily lost. Such devices should be checked and recalibrated by a professional laboratory at least once a year and preferably once a quarter. This is almost never done, especially in smaller departments or places with revenue problems. Therefore, the courts have been sold a bill of goods about the infallability of these devices and the public is at the mercy of officers who don't understand these devices. Why are things like this important to point out? Because with RADAR, the worst case is probably the lose of money to the civilian... with the Taser, it has been and always has the potential to be lose of LIFE! I for one, would never allow myself to be tasered with the newer versions. They have cranked up the voltage and the power meaning that the potential for electrocution has increased dramatically.
Tasers should not be advertised as a non-lethal alternative. Under the right (or wrong depending on how you look at it) circumstances, they are just as lethal and a more painful means of death. Misuse of "non-lethal" alternatives have caused more than one lawsuit won by the victim's family. The very famous case here in Boston during the Red Sox celebration comes to mind. In fact, the officers involved had all been "properly trained" and IIRC found to be not at fault even though the family was paid millions in hush money. The truth is that the officers KNEW they weren't supposed to use these deadly weapons in the manner that they used them and should have been found guilty of 2nd degree murder. Those were the "Hi-Tech" bean-bag guns that were touted to the public as the safe, non-lethal alternative. Riiiiiiight...
Personally, if someone pulled a taser on me, I would consider it just as lethal a weapon as a knife or gun.
