If I may, the problem with statistics is that there is no national way of recording all of these things. As a matter of fact, in studies I've read lately, the suggestion is that--especially in the 2004-05 study--the actual amount that's been reported is probably one-tenth of actual use.
I don't have up-to-date statistics on how many deaths have been proximal, but no one has directly linked the deaths with the use of the taser. They often are attributed to pre-existing situations such as excited delirium or other forms of stressors. Some medical reports will tell you that with an electrical charge, basically if you're breathing a few minutes later, any death wasn't related to the electrical charge.
To answer your question directly, I don't have those statistics available.
One thing I do want to say in response to your question is that when you ask about stun mode and probe mode, policing has changed over the years. In the olden days the officers were more upfront and physical with the subject because there wasn't danger from AIDS or there wasn't danger from a number of other things. Now the officers are using distance kinds of applications to subdue subjects more readily. You can understand from a common-sense point of view that it might be for officer safety.
