Cops beat deaf man for 7 minutes because he didn’t respond to them

An Oklahoma man was beat for seven minutes by police because he did not respond to their yelling. 64-year-old Pearl Pearson, a deaf diabetic driver who lives in Oklahoma City was hospitalized as a result of the Jan. 3rd incident. 
From The Free Thought Project:

The following is the story according to Pearl Pearson and family of what happened that night: At this time, only limited details can be provided since this case is under investigation.

1. The Oklahoma Highway Patrol pulled Pearl over late in the evening on January 3, 2014. Pearl pulled over as he should.
2. Pearl’s driver’s license indicates he is Deaf. He also has a placard in his driver’s door that says, “Driver is deaf”.
3. Pearl pulled over and rolled down his window, expecting an officer to ask for this identification. An officer struck him in the face before Pearl had the chance to do anything.  As you can see, he was struck multiple times.
4. An interpreter was never provided while Pearl was under the care of law enforcement.  Not during the booking, hospital, or time at the jail  was an interpreter provided, even through Pearl requested one.
5. Pearl was left wondering “why” the the entire time.  He has no clue why  he was beat. Pearl and his family are still not sure, but are ready for some answers.
6. Pearl’s own son is a police officer, as was his son-in-law, who is now a deputy sheriff.  He respects law enforcement and knows how to respond when pulled over.  There is no reason for someone like Pearl to be hurt like this by those who are meant to protect and serve.

The two officers involved in the seven minute altercation were identified as Eric Foster and Kelton Hayes. Both officers have been suspended with pay while the investigation into the incident continues.
No words for actions like these.
