Perhaps, but none of those images provide evidence of a "systemic" issue.
Of course, in fairness to you, proving that it's a "systemic" issue is next to impossible, even if it is system-wide.
On the other hand, police misconduct is a complex issue with many facets, and pushing "rayciiiissssss" is like putting a round peg in the middle of a much larger star-shaped hole. Sure, it might be a part of it, conceivably, but claiming that it's what makes up the whole thing is stupid.
