Tasers are not safe
Another story about someone dying after being tasered, on the heels of that Polish guy who died in Canada.
I think the problem is that a lot of these officers aren't really trained correctly. Tasers should be thought of as an alternative to deadly force. If you can use a taser, where you would have used a gun, that's good. To me, these stories generally seem to be about officers who used the taser in place of physically subduing an unarmed person. I know that it can be dangerous, but that's the job. If you've got one unarmed Polish guy and several RCMPs, your training really ought to be enough to take him down safely.
In these two cases, what would the officers have done before tasers were available? Would they have pulled their guns? If the answer is no, they should leave the tasers in the holster.
