As to whether you agree with this poor woman's political view is not the case. We all have a right to protest.
From what I have seen she clearly reversed and then drove forward to move away, if her intention was to run over any one would she have done so?. The ice officer's where probably píssed off because because of her and her wife's attitude towards them but does that justify murdering someone.
I think she had no intention at all to drive into anybody,
The force used was excessive, unfortunately typical of the USA,
Such a shame that she died because of hurty words
