Facts are unimportant to BLM

Some NFL players who are part of BLM are demanding that the NFL declare that November is anti-cop month, because 300 people have been shot by police since 2016. There is a problem with that supposed "fact." Here is the quote from the letter that the players sent to the league:

Since 2016, police have shot over 300 men and women in this country. Some of the names and stories are familiar—Jordan Edwards, Trayvon Martin, Alton Sterling, but hundreds of others are not,” 

There are a number of inaccuracies here:
1 Trayvon Martin was shot in 2012, not 2016.
2 He was shot by a private citizen in a case where the trial determined it was self defense, not by police.

When it is so easy to find lies in your letter, how can we trust anything else you have to say?
