Trayvon Martin was not shot by police. Not saying it was right, but it was not police.
But the police investigation into what happened, the way he was talked about by the police in press conferences, the support of Martin, who shot an entirely innocent person who posed no threat, and yet the police accepted Martin was right to do so under the stand your ground laws because there was no evidence he was lying (since when was that the standard of justice?)
This is also what the police are doing to black people in the US. And that’s why when a white person shoots a black person (or calls the police on them, or abuses them in the street) they feel justified in doing so, simply because of the colour of their skin.
You don’t have to be shot by police to have your life ruined. Ask any one of the 1200 black people exonerated since 1989, who cumulatively have served over 15,000 years in prison for crimes they did not commit.
Out of interest, those 1200 total almost 50% of those exonerated and yet represent 57% of the number of years served by exonerees. White people make up 37% of exonerations, but represent only 32% of the number of years served.
The biggest factor leading to wrongful convictions is overzealous police officers working to make a case where none actually exists. This is what the US are doing to black people.
