I carry a Taser everyday at work and have successfully used it in the line of duty 7 times now. They are a fabulous weapon for our intended purpose, incapacitate, control, capture and cuff.
With that being said, I would NEVER carry one as a primary defensive weapon outside of work and I would NEVER recommend the Taser as an alternative to carrying a concealed firearm. Here's why.
1) One shot, you miss with that first cartridge and now you've got to go hands on or hope you can run faster than BG because BG is pissed that you tried to tase him, and drive stuns are much much less effective than probe shots.
2) BG may have a gun, simple enough.
3) 30 seconds is not a lot of time. On a dark night in an urban setting, if there are no businesses open to call for LE or you call from a cell phone and it takes 4- 5 minutes for them to arrive, you could be in trouble if BG decides to go hunting for you now armed with your Taser.
4) Laws regarding civilian carry of Taser devices are very unspecific and underdeveloped. IF you tase someone and they fall over, hit their head on a parking block (or whatever else) and die from subdural bruising or intracranial bleeding (real conditions that are fairly easy to inflict) you are now being charged criminally and subject to the same civil lawsuits as if you had shot the person with a real firearm in the first place. The law does not protect you simply because you carried a "less lethal" device.
As far as LEO's who think Taser's are the be all end all of LAWE work, they need to grow up. For an LEO every tool has a time and a place for it's proper and effective application and statements like this
But if I have to stop someone this second, I would choose the Taser.
are foolish and misleading. LEO Taser training classes are not usually conducted under real life conditions, they are conducted under optimum conditions.
Effective use of a Taser has many variables involved due to the fact that you are firing 2 seperate projectiles along different lines of fire at one time and beyond that they are designed to have very low penetration. So, for all of you in northern states, when the BG in the poofy down jacket approches and you tase him, he more than likely may not even notice.
As a civilian if you
truly feel you need to protect yourself from possible
life threatening harm buy a gun,
train with it extensively, study the laws regarding weapons carry in your area, get the proper licensure and carry a firearm. If you can't justify carrying a firearm then you shouldn't be carrying a Taser either.
P.S. The bull in the above posted video was shot with an animal Taser which is 7 times stronger than Tasers for human use and is designed to be used on cattle and zoo animals. If that Taser were used on a human your muscles would contract so violently they would tear themselves away from the bones.
