Fair point, and yeah war on police is a completely subjective perception.
That being said, are these reported assaults or convictions? Body count is a reliable measurement, whereas reported numbers can be fudged and convictions can be wrong (tho I would put more faith in convictions than reports).
Id say any that have been reported but I'm not 100% sure. It looks as though they get the same stats as the Officer Down Memorial page and they keep a pretty accurate count.
And the thing about non-convictions is that it doesn't necessarily mean it didn't happen. Domestics are the poster child for that, the victim FREQUENTLY drops the charges or testifies in favor of the offender.
Literally had a guy use his g/f's head as a battering ram through a window, a wall, then lock her in a head lock and choke/drag her down a hallway...all in front of their 5 year old son. Took warrants out, checked on her multiple times over the next week...only to have him back a week and a half later and then PROTECTED him while we tried to apprehend. He's still on the run.
Sorry...ranting...
Anyway...the thing about crime statistics are how they're classified, as events or individual crimes. For example, the FBI categorizes stats by events, such as a Strong Armed Robbery that, while getting away, results in a wreck with injuries or even a fatality. IIRC, they only classify that event by the crime that set the wheel in motion, Strong Armed Robbery, a Class C Felony...even though it could result in a conviction of vehicular homicide. So, in other words, the only statistic that would be recorded for that entire event would be a robbery, nothing more.
Now that I've thoroughly muddied the waters...
