the knockout game got a little press, although imagine if White people were going around attacking blacks- flags would be at half-staff and obama would be arm in arm with Sharpton marching somewhere. But this is relatively new. Slashing people in the street. No need to report on it, and there is certainly no motive. They are (cough-cough) random
I would think by this time people would be more on their guard when in the presence of a certain demographic - if they ever have to be in the presence of said demographic.
Stupid to even be texting around superpredators, just because you can easily lose the phone.
I'll bet the great majority of Americans have little or no knowledge of all the slashings going on. I doubt they know little about the "polar bear beatings" as well. Because the national media doesn't report them. I should say, I don't think they ever do. I don't watch the alphabet news networks.
But the staggering amount of violent, black crime is seldom covered by the lib news media. Furthering the false narrative of racist whites committing violence against blacks is more important to them.
