I saw this report a few months ago, so bear with me if it has an inaccuracy.
My agency currently sits around 6,300.... For 2013 (last year a full report is completed on) we had 7 reported shooting incidents. At least 1 (possibly 2) of those were suicides by Agents off duty. We are Feds, not street cops, so we don't have to deal with drunks and domestics. We deal with kilos, alien smuggling and human trafficking. But we don't have the same threat level that a beat cop has at 2am, while by himself. Street cops are far more likely to have to use force.
The point us, The numbers of shootings are incredibly low for us. But we chase/arm bar/punch/and tackle quite a bit when needed.
We have a report put out annually like the NYPD. Every A/D, every intentional shooting, every shooting of a dog or injured animal must be reported and documented. We also have to document use of OC/Baton/Taser. But those are rarely used.
I will try and find the report on line and see if it is official use only or if I can link it...
