Do you not remember what happened after the the acquittal of the officers that brutally beat King? The LA riots happened. The video was what catalyzed so many to action even when the truth of police brutality was well known before that.

This is true of Eric Garner which was also caught on video and lead to large demonstrations.

And again with Philando Castile where the video showed Castile totally complying with officer orders, yet was still shot dead by that police officer. Again demonstrations against police brutality.

Its the video that makes people take notice. Sadly, it doesn’t sound like we have video of Ruben Ray Martinez final moments yet.
