This is the kind of frustration by police we can exploit. The police lost their cool. No child should be beaten for standing on a planter on an open street. If your parent beat you down and handcuffed you every time you did something a bit youthful in the grocery store, you would be taken away from your parents.
These Dallas police officers did not act properly, and they should be held accountable by their supervisors and the good citizens of Dallas for being less than adult in the midst of a non-violent march.
To the protesters, I quote Tolstoy', who quoted Jesus: "Resist no evil." This means that you should be happy with your victimhood and continue to stand. But stay off the planters from now on.
