These things are all tied together. The calls for Police Reformation started in ~2014 with the elimination of carding. It was overlapped with Black Lives Matter. Since then, stats show that the Reformation and advocacy of BLM has led to a significant
increase in shootings, homicides, and violent crime a decade of decline - or looked at from a wider angle, 40 years of decline.
To me, Police Reformation is a code word for allowing criminals to get away and create more havoc in the city.
This is not a well evidenced statement.
The link you provided shows higher absolute homicide totals in 2005 and 2007 that any year in the last decade, excepting the year of the Van Attack, which was anomalous and surely not the result of BLM or Carding, the suspect being a white, incel.
Further, during the period in question, the City's population increased by 20% from 2.5M to 3M.
That means stats require per capita weighting.
If we remove the highest and lowest numbers from the 5-year period centred on 2007, and average the balance, we get 73 homicides per year.
If we do the same, for the 5 year period centred on 2017 we get 72
Lets apply those 2 on a per 100,000 basis to compare.
2007: 2.92 homicides per 100,000
2017: 2.43 homicides per 100,000
This suggests declining crime.
Yes, if you cherry pick the lowest 5 years you get a lower number; but we're still down decade over decade
Further, in this year's year-to-date totals, we see a number well below that of 2016 or 2018
The assertion you've made is illogical and without fundamental support, even in the niche of homicides.
