American Police had better explain what Police job is to people not only Black but others.
If the case that Police kill Black people more and more,
People can't trust Police job.
The case that Police must explain,
1, The attitude that After Police say, "Hold up" "Freeze"
2, The case that Police use the gun.
Police must explain those cases clearly.
President Obama says,
"One America is very important."
People never hope TWO AMERICA.
