If you just hear the last part of the quote, it sounds bad especially if you feel strongly about the Black Lives Matter movement.
If you listen to the entire video you understand more of what LeBron is trying to say.
This is someone who is one of the most famous people on earth who says he is concerned about his son being pulled over by the cops and something tragic happening just because his son is black.
What he is saying at the end is that while he has that fear, he does understand not all cops are bad and some cop related shootings are totally justified. That everyone’s life should matter, but he used the hot button phrase all lives matter.
The sad part is the people who are racist and prejudice will use the last part to make it seem LeBron is anti-black lives matter and some black people will only hear the last part and assume the same.
Listen to the whole thing, don’t twist the context of what he is trying to say, then make your own opinion.
