You raised that point
in a context though, talking about a specific event, under a greater conversation about a specific article, and without qualification. If you're talking about how your dad got stabbed 30 times by muggers and somebody blithely comments about how that seems like a pretty reasonable number of stabbings based on standard mugging procedure, you'd take it as -- at best -- off-topic and cruelly dismissive of the core issue and at worst an attempt to distract from or even justify it.
If you'd said, "we should focus more on how the shooting started in the first place and the sheer incompetence and us-vs-them mentality that allows cops to cross the violence threshold so constantly & without consequences, rather than the specific number of bullets lodged in various things" you might have had a better and more constructive conversation. As it stands, you've doubled and tripled down on that not mattering, and I think it gives an impression to readers.
Very, very off topic, but I do think it's kind of weird to magdump in a public space. We're taught to be extremely cautious of what's behind our targets at all times, and the corollary to 'once the tool comes out, you use it' is 'try not to bring the tool out at all costs', which you conveniently leave out as well. Finally, I don't know how good you are in terms of time to reacquire but squeezing more than 3 or 4 in a row definitely throws my aim off (even with a relatively heavy CZ75 SP01 or my million pound 1911 - I imagine the cops use a more polymer-intensive and therefore lighter weapon) (also assuming still that these are handguns and not long guns of some sort), so just indiscriminately dumping 17+1 or whatever doesn't strike me as a viable approach to hitting your target.
Cops do a very poor job of all of this, and people rightly want their poor performance to be held to account.
