At the end of the day, I think it all comes back to this: perception. When I saw the picture of the officers riding a horse, I think it was cool mainly because it would really be easier for them to pursue offenders in "tight" corners which might not be accessible by car.

Looking at the picture and, I am just wondering, will this same people be yelling injustice, racism and whatnots if the arrested person came from a white background?

I understand that it was necessary to ensure that the offender will not run away- thus the rope and the handcuffs were there.
