Initially there was only one officer there, getting Brooks out of the drive-through and into a parking spot and doing an interview, etc.
...........
That officer decided on a field sobriety test which requires another officer as a witness.
........
Response time and doing the field test took time.
..........
Once Brooks failed all the sobriety tests and the officers chose to arrest, they should have called in backup.
..........
The suspect was drunk, not thinking clearly, going back to prison, yup, the likelihood for resistance was high, get backup.
“Once Brooks failed all the sobriety tests and the officers chose to arrest, they should have called in backup.”
Yeah but he had them conned into thinking he would be reasonable and cooperative instead of going berserk.
