Grabbing black people's phones prank

I'm paraphrasing himself here from a friend's FB on this:

which is I completely fail to see the humor in this and I'm sensing a much more insidious motive at play
because these white guys are mainly targeting lower income blacks and Latinos in the "urban" part of the city.

It's very subtle,but it's like they are trying to project the stereotypical accusation that "these people" are unreasonable violent rage filled savages.

Although they(the "pranksters") are the ones violating these citizens Constitutional Rights.
